Digital Fingerprinting: Google launched a new era of tracking worse than cookie banners | Tuta
Digital Fingerprinting: Google launched a new era of tracking worse than cookie banners | Tuta
So I guess for Firefox users it's time to enable the resist fingerprinting option ? https://support.mozilla.org/en-US/kb/resist-fingerprinting
You can also use canvas blocker add-on.
Use their containers (firefox multi-account container add-on) feature and make a google container so that all google domains go to that container.
If you want to get crazy, in either set in about:config or make yourself a user.is file in your Firefox profile directory and eliminate all communication with google. And some other privacy tweaks below.
This is why I like Lemmy, never knew canvas blocker was a thing. Thank you.
I'm still trying to wrap my head around fingerprinting, so excuse my ignorance. Doesn't an installed plugin such as Canvas Blocker make you more uniquely identifiable? My reasoning is that very few people have this plugin relatively speaking.
I use (and love) Firefox containers, and I keep all Google domains in one container. However, I never know what to do about other websites that use Google sign in.
If I'm signing into XYZ website and it uses my Google account to sign in, should I put that website in the Google container? That's what I've been doing, but I don't know the right answer.
Why does it do this?
PS grateful for this option!
Some math functions have slightly different results depending on architecture and OS, so they fuzz the results a little. Here's a tor issue discussing the problem: https://gitlab.torproject.org/legacy/trac/-/issues/13018
I've used this. The only annoyance is that all the on-screen timestamps remain in UTC because JS has no idea what timesone you're in.
I get that TZ provides a piece of the fingerprint puzzle, but damn it feels excessive.
I mean it doesn't hurt but as far as I can tell, it doesn't actually block fingerprinting, it blocks domains known to collect and track your activity. The entire web is run on Google domains so that would be nearly impossible to block.
The crazy part about fingerprinting is that if you block the fingerprint data, they use that block to fingerprint you. That's why the main strategy is to "blend in".
The crazy part about fingerprinting is that if you block the fingerprint data, they use that block to fingerprint you. That’s why the main strategy is to “blend in”.
So, essentially the best way to actually resist fingerprinting would be to spoof the results to look more common - for example when I checked amiunique.org one of the most unique elements was my font list. But for 99% of sites you could spoof a font list that has the most common fonts (which you have) and no others and that would make you "blend in" without harming functionality. Barring a handful of specific sites that rely on having a special font, that might need to be set as exceptions.
Privacy Badger anyone?
But does privacy badger also act on the canvas APIs & cie. ?
It annoys me that this is not on by default...
It's a nice feature for those that actively enable it and know that it's enabled, but not for the average user. Most people never change the default settings. Firefox breaking stuff by default would only decrease their market share even further. And this breaks so much stuff. Weird stuff. The average user wants a browser that "just works" and would simply just switch back to Chrome if their favourite website didn't work as expected after installing Firefox. Chrome can be used by people who don't even know what a browser is.
Does ublock do this?
No
Please don't enable this blindly. A lot of modern websites depend on a bunch of features which will simply not work with that flag enabled. Only do it, if you're willing to compromise and debug things a bit
So, manifest v3 was all about preventing Google's competitors from tracking you so that Google could forge ahead.
It was never about privacy, it was supposedly about security, which there is some evidence for. There were a lot of malicious extensions. The sensible thing to do would be to crack down on malicious extensions but I guess that costs too much money and this method also conveniently partially breaks adblockers.
The fewer of your competitors who have the data the more valuable that data is.
Would it be possible for a browser or extension to just provide false metadata in order to subvert this type of fingerprinting?
So from what I understand, theres 2 common ways that browsers combat this. Someone add to or correct me if I'm wrong.
Ex: Everyone wearing black pants and hoodies with the facemasks. Extremely hard to tell who is who.
Ex: look like a dog in one place, a cat in another place. They get data for a dog but that doesn't help build anything if the rest of the data is a cat, hamster, whatever. No way to piece it together to be useful.
In both my examples, there are caveats. Just because everyone dressed the same doesn't mean someone isn't taller or shorter, or skinnier or fatter. There can still be tells to help narrow down. Or a cat that barks like a dog suddenly is more linkable to a dog if that makes sense lol.
In other words it still depends user behavior that can contribute to the effectiveness of these tools.
EDIT: got distracted. To answer your question I don't think so. I think it's more about user behavior blending in or being randomized. I think the only thing an extension would be able to do is possibly randomize the data but I'm unsure of such an extension yet. These aren't the only options, these are just ones I've read about recently. Online behavior, browswr window size, and I'm sure so much more also goes into it. But every little bit helps and is better than nothing.
EDIT2: Added examples for each for clarity.
Mull is discontinued unfortunately, although I think it got forked?
The first point is flawed and even TOR doesn't execute javascript because it's impossible to catch everything when you give the server full code running capabilities.
The second point is more plausible but there's an incredible amount of work to do to fix this. Like, needing to rework browser engines from ground up and removing all of the legacy cruft. Brave is not capable of this and never will be no matter what they advertise because it doesn't have it's own engine.
That being said, these tools will get you quite far against commercial fingerprint products especially ones used for Ads but that will also ruin your browser experience as now you're just solving captchas everywhere 🫠
No. Anything that executes Javascript will be fingerprinted.
That being said it depends who are you fighting. For common commercial tools like Cloudflare fingerprinter it might work to some extent but if you want to safeguard against more sophisticated fingerprinting then TOR and no JS is the only way to combat this.
The issue is that browsers are so incredibly complex that it's impossible to patch everything and you'll just end up getting infinite captchas and break your browsing experience.
Yes. There is a firefox extension called Chameleon that does this.
Yes but that metadata is also used to serve you the webpage, so if you spoof it, the page may not load properly.
Others have mentioned what Firefox/etc do, but another option is a PiHole. If you can't look up the IP for an advertiser URL, you don't load the JavaScript to begin with.
This has been the case for years. I develop fingerprinting services so AMA but it's basically a long lost battle and browser are beyond the point of saving without a major resolution taking place.
The only way to resist effective fingerprint is to disable Javascript in its entirity and use a shared connection pool like wireguard VPN or TOR. Period. Nothing else works.
How can you live with yourself?
I do it as a security measure for private institutions and everyone involved has signed contracts. It's not on the public web.
I know right. I was offered a job at a betting site and online casino with those addictive games and shit. Gave that a hard pass, said no thanks, don't think that's the right business area for me. I would feel so dirty going to and coming from work every damn day.
Disabling JavaScript entirely is another data point for fingerprinting. Only a tiny fraction of users do it.
Besides, without JavaScript most websites are not functional anymore. Those that are are likely not tracking you much in the first place.
Yeah unfortunately disabling JS is not viable option tho onion websites are perfectly functional without JS and it just shows how unnecessarily JS had been expanded without regard for safety but theres no stopping the web.
I disable JS with noscript.net and it really is an enormous pain. It has some security advantages, like I don’t get ambushed so easily by an unfamiliar site and pop ups. I often will just skip a site if it seems too needy
This is what I've been saying for months in the reddit privacy sub and to people IRL. Some people seem perfectly happy to just block ads so they don't see the tracking. Literal ignorance is bliss. Most simply don't have time or wherewithal to do the minimal work it takes to enjoy relative "privacy" online.
FWIW, any VPN where you can switch locations should do the job since the exit node IPs ought to get re-used. My practice is to give BigG a vanilla treat because my spouse hasn't DeGoogled, and leave anything attached to our real names with location A. Then a whole second non-IRL-name set of accounts usually with location B with NoScript and Chameleon. Then anything else locations C, D, E, etc.
Ugh... This all sucks.
What are you people trying to hide ???? /s
So… how effective is it? The fingerprinting. I’m guessing there are studies? Also don’t know whether there’s been legal precedent, ie whether fingerprinting has been recognized as valid means of user identification in a court case.
It's super effective but there are very few real use cases for it outside of security and ad tracking. For example you can't replace cookies with it because while good fingerprint is unique it can still be fragile (browser update etc.) which would cause data loss and require reauth.
Usually fingerprint plays a supporting role for example when you do those "click here" captchas that's actually just giving the browser time to fingerprint you and evaluate your trust to decide whether to give you a full captcha or let you through. So fingerprint is always there in tbe background these days tho mostly for security and ad tracking.
As for court cases and things like GDPR - the officials are still sleeping on this and obviously nobody wants to talk about it because it's super complex and really effective and effects soo many systems that are not ad tech.
Just in time for their prophet, Curtis Yarvin, to be pushing a full-scale surveillance state!
Googlers aren't on our side. They want to rule. They think being a fucking admin on a server makes them cut out to run society.
They want to tear down democracy and basically replace it with administrator rules and access control lists.
Googlers aren’t on our side
They never were, out interests just aligned while they were growing market share. They have that now, so there's no more reason to stay aligned.
Corporations aren't your friend, but they can be momentary allies. People should've bailed once IE was dethroned, but here we are...
So I thought this is never going to fly under GDPR. Then the article goes on to say:
Many privacy laws, including the EU’s GDPR and California’s CCPA, require user consent for tracking. However, because fingerprinting works without explicit storage of user data on a device, companies may argue that existing laws do not apply which creates a legal gray area that benefits advertisers over consumers.
Oh come on Google, seriously? I remember a time when Google were the good guys, can't believe how they've changed...
Google were maybe seen as the good guys back in the days of Yahoo search, and perhaps the very early days of Android.
But those times are so long passed. Google has been a tax-avoiding, anti-consumer rights, search-rigging, anti-privacy behemoth for decades now, and they only get worse with each passing year.
In other words, they went public and must now maximize gains for shareholders.
for decades now
You should drop that S. The company has only existed for a little over 2 decades and Android hasn't been around for much more than 1. Yes they've become an evil fucking corporation but let's not exaggerate for how long.
That time was like 20 years ago, dude
It's still sad to see the development. We're allowed to mourn things that happened long ago, you know.
Oh absolutely. At this point I'm not surprised anymore that they turned to shit, it's more like I think they've hit rock bottom already but they manage to surprise me with new ways to dig their hole even deeper.
Yeah, I have an anti fingerprint extension installed in Firefox, and immediately no Google site will work anymore, all google sessions break with it while most other sites just continue to work.
I'm working to rid myself completely from Google, my target being that I will completely DNS block all google (and Microsoft and Facebook) domains within a year or so. Wish I could do it faster but I only have a few hours per weekend for this
Mind sharing what extension you use?
Hi, here are the extensions I use in FireFox/Librewolf (all will work in Chromium too, but I don't recommend Chromium browsers):
uBlock Origin: A lightweight and efficient wide-spectrum content blocker.
Decentraleyes: Protects you from tracking through free, centralized content delivery. (not recommended alongside uBlock Origin; see the reply below)
CanvasBlocker: Protects your privacy by preventing websites from fingerprinting you using the Canvas API.
Ghostery Tracker & Ad Blocker - Privacy AdBlock: Blocks trackers and ads to protect your privacy and speed up browsing. Also has a handy feature that automatically rejects cookies for you. (not recommended alongside uBlock Origin; see the reply below. You can disable the ad blocking functionality and keep the cookie rejection function).
KeePassXC-Browser: Integrates KeePassXC password manager with your browser.
NoScript: Blocks JavaScript, Flash, and other executable content to protect against XSS and other web-based attacks (note: you will be required to manually activate javascript on each web page that you visit, but this is a good practice that you should get used to).
Privacy Badger: Automatically learns to block trackers based on their behavior. (not recommended alongside uBlock Origin; see the reply below)
User-Agent Switcher and Manager: Allows you to spoof your browser’s user-agent string (avoid creating a unique configuration; opt for something common, such as Chrome on Windows 10).
Violentmonkey: A user script manager for running custom scripts on websites (allows you to execute your own JavaScript code, usually to modify how a website behaves or block behavior that you don't like. VERY useful. Check out greasyfork for UserScripts).
Firefox Translations: Provides on-demand translation of web pages directly within Firefox.
Flagfox: Displays a flag depicting the location of the current website’s server.
xBrowserSync: Syncs your browser data (bookmarks, passwords, etc.) across devices with end-to-end encryption.
Plasma Integration: Integrates Firefox with the KDE Plasma desktop environment (for linux users).
What search engine do you use?
I want to do this but really the only thing holding me back is my phone.
Which is why I had hoped the EU would ban all forms of fingerprinting and non-essential data tracking. But they somehow got lobbied into selecting cookies as the only possible mechanism that can be used, leaving ample room to track using other methods.
How would that even be enforced?
same way other regulations are enforced: fines
Not sure how to effectively do that, but I reckon it would be no different than the cookie mess today. Which unfortunately is, hardly ever. The big GDPR related fines can still apply. Let's say a data set is leaked that includes tracking data that was not necessary for the service to have, then the company can receive a hefty fine. As long as the fine is larger than the reward, it might not be worth it for the company to track you anymore.
Further evidence that a Republican government in the USA results in private organisations pushing the bar as far as they can.
In Reagan's time it was Wall Street. Now it's Silicon Valley.
You want private organisations working for your benefit and not that of their shareholders? You need a government that actually has the gumption to challenge them. The current US government is 4 years of a surrender flag flying on the white house.
Or we could bin off this fucking failed neoliberal experiment, but that's apparently a bit controversial for far too many people
Having the gall to suggest we not allow less than 3000 people to own all of the worlds supply lines, media platforms, institutional wealth, construction companies, dissemination platforms, politicians, private equity firms and the single largest interconnected (private or otherwise) espionage and social engineering plot known to mankind?
You fucking tanky you! Go back to Russia!!!
Republicans aren't the problem here, they're a natural result of a two party system. If you have a coin, half the time you'll get the "good" side, and half the time you'll get the "bad."
And this isn't to say either side is consistently "good" or "bad," parties rarely stick anything. The deregulation you're complaining about started under Jimmy Carter, affectionately called "the great deregulator." In fact, many (most?) of Carter's changes took effect during Reagan's term, and it was incredibly successful.
However, for some reason Democrats are now against deregulation, probably because Republicans took the credit and Democrats needed to rebrand.
That doesn't imply that Trump's deregulation is "good," it just means deregulation isn't inherently "bad."
Good thing I erased Google out of my life a decade ago meaning I can much easier block even more of their everywhere present garbage and not have issues.
Dropped your 👑, king
Beware, the current administration might send you to Gitmo if you don't kneel to King Trump!
I go to pornhub every morning to check out the articles. Lately I've noticed that they have exactly the kind of articles I'm interested in always at the top two rows and then a bunch of stuff I'm not really into elsewhere. They are definitely testing stuff.
I too go to pornhub for the articles.
I thought people go to pornhub for the lack of articles
I go to pornhub for the definite article
Idk, I see a lot of "a", "an", and "the" there.
This article actually shares what changed, as opposed to just asserting that there was a change.
It would be nice to hammer a manually created fingerprint into the browser and share that fingerprint around. When everyone has the same fingerprint, no one can be uniquely identified. Could we make such a thing possible?
Not really. The "fingerprint" is not one thing, it's many, e.g. what fonts are installed, what extensions are used, screen size, results of drawing on a canvas, etc... Most of this stuff is also in some way related to the regular operation of a website, so many of these can't be blocked.
You could maybe spoof all these things, but some websites may stop behaving correctly.
I get that some things like screen resolution and basic stuff is needed, however most websites don’t need to know how many ram I have, or which CPU I use and so on. I would wish for an opt-in on this topics: So only make the bare minimum available and ask the user, when more is needed. For example playing games in the browser, for that case it could be useful to know how much ram is available, however for most other things it is not.
Tor browser
And Mullvad browser
This is called Tor
No it isn't.
And this is really important. If you go on Google tracked websites without tor, Google will still know it's you when you use tor, even if you've cleared all your cookies.
Tor means people don't know your IP address. It doesn't protect against other channels of privacy attack.
Tor browse
Leave everything default and you'll look like every other Tor browser user.
Time for a user agent switcher. Like "Yeah, I swear, I'm a PS5, that has only monospaced comic sans insrelled"
Fingerprinting unfortunately uses more than useragent strings. It takes hashes of data in your browser from a javascript context that is not easily masked or removed. For example, it might render a gradient of colors projected onto a curved 3d plane. The specific result of this will create a unique hash for your GPU. They can also approximate your geolocation by abusing the time-to-live information within a TCP packet, which is something you can't control on the clientside at all. If you TRULY want to avoid tracking by google, you need to block google domains in your hosts file and maybe consider disabling javascript on all sites by default until you trust them. Also don't use google.
How must it feel being clever enough to come up with these ideas and then implement them for companies invading everyones privacy for advertisement revenue and malicious information serving or stealing.
I guess they sleep soundly on a fat bank account.
Jokes aside, keep in mind that the idea of fingerprinting is that your computer's configuration is as unique as a fingerprint (e.g., your monitor is x resolution, you are on this operating system, you are using these following extensions in this browser, you have these fonts on your system).
Setting your user agent to something super unique is basically shining a spotlight on yourself.
It's way worse than that.
Even if you somehow magically have the same settings as everyone else, you're mouse movement will still be unique.
You can even render something on a canvas out of view and depending on your GPU, your graphics driver, etc the text will look different...
There is no real way to escape fingerprinting.
Digital fingerprinting is a method of data collection – one that in the past has been refused by Google itself because it “subverts user choice and is wrong.” But, we all remember that Google removed “Don’t be evil” from its Code of Conduct in 2018. Now, the Silicon Valley tech giant has taken the next step by introducing digital fingerprinting.
Oh, forgot to mention - we're evil now. Ha! Okay, into the chutes.
Google removed “Don’t be evil”
Still parading that lie around? It's easily verified as false. Their code of conduct ends with:
And remember... don’t be evil, and if you see something that you think isn’t right – speak up!
Time for meshnet?
Google can't fingerprint you very well if you block all scripts from Google.
This breaks all kinds of stuff though. A ton of sites use Google for captchas.
I just don’t use any sites like that. If a site is using something other than Turnstile from Cloudflare, then I refuse to use it. I haven’t really experienced any inconvenience myself with this policy, but obviously I don’t depend on any sites that require recaptcha.
But you can allow/block any elements per site, or globally, which makes it trivial to block all unwanted scripts except on specific sites. So there is nothing preventing you from only exposing yourself to Google on the few sites you use that need those scripts.
Using Mullvad Browser + Mullvad VPN could mitigate this a little bit. Because if you use it as intended (don’t modify Mullvad browser after installation) , all Mullvad users would have the same browser fingerprint and IPs from the same pool.
The problem is it's all or nothing. You must foil IP address, fingerprint, and cookies - all three at once.
Mullvad browser might make your fingerprint look similar to other users, but it's not common is the problem. Test it with the EFF Cover your tracks site.
And now Mullvad has all the data
Mullvad, (the vpn, I have not tried the browser) uses a single account number as both name and password, no emails. It allows for multiple anonymous payment methods and it's open source.
Sliiiiightly more trustworthy than Google imo.
If you don't trust anyone the internet (or any net you don't fully control yourself) is not something you will use.
Practical security is a matter of threat-modeling and calculated risks.
Mullvad has a good track record, but if you know of better alternatives that don't require building it yourself, please share!
And Mullvad is not in business if selling user profiles to advertisers, at least as far as we know
I know nothing, but isn’t some pieces of Google software to be found on many sites that aren’t Google or YouTube?
Yes, a lot of websites embed Google Analytics, or more nefariously Google Fonts.
And recaptcha. And Google-hosted Javascript libraries. And youtube embeds.
Yes, mainly Analytics, sometimes Maps.
what?
new? isn't this at least like a decade old method of tracking?
You'd THINK the article would link to a source about the fingerprinting in question instead of 90% filler slop and ads for their own service... Anyone got a link?
What is it you're looking for? Do you want to know what kinds of information is used for fingerprinting?
If so, check out coveryourtracks.eff.org and amiunique.org.
But why would any browser accept access to those metadata so freely? I get that programming languages can find out about the environment they are operating in, but why would a browser agree to something like reading installed fonts or extensions without asking the user first? I understand why Chrome does this, but all of the mayor ones and even Firefox?
Because the data used in browser fingerprinting is also used to render pages. Example: a site needs to know the size of browser window to properly fit all design elements.
Just for an example that isn't visible to the user: the server needs to know how it can communicate responses to the browser.
So it's not just "what fonts do you have", it also needs to know "what type of image can you render? What type of data compression do you speak? Can I hold this connection open for a few seconds to avoid having to spend a bunch of time establishing a new connection? We all agree that basic text can be represented using 7-bit ASCII, but can you parse something from this millennium?”.
Beyond that there's all the parameters of the actual connection that lives beneath http. What tls ciphers do you support? What extensions?
The exposure of the basic information needed to make a request reveals information which may be sufficient to significantly track a user.
I fucking hate this. Let me zoom, stop reacting and centering omfg.
Firefox has built-in tracking protection.
I know that it has that in theory, but my Firefox just reached a lower score on https://coveryourtracks.eff.org/ (which was posted in this threat, thanks!) than a Safari. Firefox has good tracking protection but has an absolute unique fingerprint, was 100% identifiable as the first on the site, as to Safari, which scored a bit less in tracking but had a not unique fingerprint.
Great read from Tuta on thia topic. It's been an issue for a while but Google going full force publicly on it causes this issue to grow greater.
I left a comment replying to someone further down about how this can be at least a little combatted and how it is with browsers. (At least to my minimal knowledge of it)
I just wish Tuta put more effort into their product than their marketing.
I noped out because of them not letting me have any control over my emails outside of asking them for a dump. But reading the support reddit is just brutal.
I personally have never used them. I use Proton myself (despite some news) and haven't had any issues. I've heard Tuta is also great but I think one of the cons of privacy mail is that they're not going to be nearly as polished as the big players like Gmail or outlook.
Do you have a link for those reviews of Tuta email?
its captcha v3, its the same thing reddit uses to catch bots and ban evaders, apparently its expensive for reddit so they only mostly use it for ban waves.
PiHole
AdAway
Burn the ads down.
Sadly, neither will truly protect you from fingerprinting.
They can block domains known to collect fingerprinting data but yes, they don't block fingerprinting itself.
When you go to The Verge and there's a full-screen pop-up about "our 872 partners store and access personal data, like browsing data or unique identifiers" those are all databrokers, and it's not just them, it's a fucking epidemic on the internet of sites that sell user data. The web has a cancer and it's called advertising.
Sure, but look at it this way. Fingerprints are benefiting the advertisers, and their purpose is to better target ads. Well I say fingerprint the hell out of everything, but I'll make sure no ads get through. If we all do that, what's the added value of fingerprinting then?
Like, why not? The article says:
“And this is exactly why Google wants to use digital fingerprinting: It is way more powerful than cookie-based tracking, and it can’t be blocked for instance by switching to a privacy-first browser.”
If I use Firefox and Firefox doesn’t send any fingerprint to the website, then how is it identifying me?
I get that if you use Android (which is normally tied to Google), you’re still subject to see it on Google websites, but how will it work otherwise?
We're all gonna need to use whonix for basic shit now
I wonder how safe is Apple ecosystem from this.
Lol
Daily plug for Cromite, which is explicity built for anti-fingerprinting (through not just blocking, but spoofing and stripping systems out) and de-Googling:
@misk I think your federation software is broken. In Mastodon, the urls in your posts just lead back to themselves every time, not out to an external article.
Sir, this is a Lemmy’s.
@mightyorbot @misk I'm using Friendica. From here, the links are normal. As it's also not Lemmy, I guess it's a Mastodon-specific (or even instance-specific) problem.
I'm not sure if you'll get this reply @mighty_orbot@retro.pizza, but here's the link visible from Lemmy itself: https://tuta.com/blog/digital-fingerprinting-worse-than-cookies.
Your method of accessing this Lemmy community seems not to be working on your side somehow. You might try a different app - I've never used Mastodon so I don't know what might work.
@OpenStars That was my point. I can open the post on its own server and see it as intended. But the federation part of the Lemmy (?) software is clearly not generating the right data.
Mbin will now load pictures within the comment?!
@mightyorbot@retro.pizza @misk@sopuli.xyz same thing happens for me, i use sharkey on my instance (misskey fork) and i have to go to that linked post and click the link there to access it

Adult People accepting these material conditions disgust me.
But as society we got what we deserve, get fucked by daddy and asking for seconds because convenience and you can't expect a peasant to have any agency
Not sure why youre being downvoted your not wrong. The peasants need to sack up and help dismantle this shit
These statements appear to be insulting to them?
However, clearly politely explaining shit to them doesn't work so I am just shit posting until I am dead or we hit critical mass of freedom enjoyers which ever one comes first.
Unlock Origin, Ghostery, and what else? Scriptmonkey maybe?
They'll stop it.
Nope. Try Creep.js. It is real creepy.
Ooooh, no they won't stop this. It's the workaround for tracking with all the things you just mentioned.
You have to either mask the fingerprint like how Brave does, or spoof the headers and block JS to make the fingerprint useless.
If that's what it takes. It's worth it.
I don't bother. I know they know everything about me already, and that I'm not an important person. As such, I wonder why it matters.
Username checks out.
Behaviour is tracked in order to be influenced.
The only thing that matters in government politics is public opinion.
