Have you ever disabled adblock for a well made site? If so, on what site?

Never. It’s a malware vector.
- Yeah, it is a safety tool.
  I could disable it for a site that doesn't have anything to block, but then leaving it on has no downsides. Like I don't really need it for lemmy when zero things are blocked, but why turn it off when there is always the possibility that an instance could be hacked?

Nope. I simply refuse to watch ads.
Either the website or their author will have provided the means to support them directly, or I won't. And if they try forcing ads on me, I quit using their website.
I'm fine with spending money to support content or services I appreciate. I refuse to waste a second of my life watching ads. That's the reason why we have not owned a TV since the early 00s: my spouse and I realized we were screwed as, at least here in France, we were supposed to pay for watching TV but still would have to watch ads, more and more of them for that matter. So, gone the TV.

Once upon a time, long ago, I did it for reddit but they burnt that good will to the ground. Give a corporation an inch and they'll take as many miles as they can before someone stops them: I block everything now and if it won't load then I don't bother with it. If it's really important I'll still find a way to view it but never again will I allow ads anywhere I can help it. Advertisements are a very serious threat to security and privacy. Malware and scams are routine in ads, even ads from known corporations that are supposedly safe, like Google.

Not for a well made one, but one I made.
I was testing some shitty PHP code and turned off adnausem just incase it was messing with my shitty PHP code. But I should have known my shitty PHP code was broken and it wasn't adnausem.
- PHP
  Well there's yer problem lmao

If ads went back to a static image I would turn off my adblocker.
But, most sites are just too annoying without an adblocker. If a site will not function with an adblocker I leave the site.

Sites are rarely involved in picking what ads get displayed. I know there's controls with your ad provider that let you say it's a tech site or a cooking site and similar ads will be shown but that's not enough control to stop somebody malicious. The FBI recommends ad blockers for safety, not because they find them annoying.

I disable it for very few sites. These sites provide nice and free niche content but don't show any ads. I just disable so that the tracking works for sure, to motivate them continue running the site.

Do you ever have sex without protection because the other person looks "clean"?
- Virgins but use protection anyways for birth control.

There are a few car specific forums still running vBulletin that I pop the blocker off for. E.g, cb7tuner.com. They use unobtrusive banners on the top and bottom of the page and I do want to support them. Those are the only exceptions though.

Rules to unblock:
Visit site, non obnoxious pops that says please unblock and allowed me to continue anyway. After I continue without unblocking, it has reasonable, clean ads in the margins, not distributed throughout the content.
I will them permanently unblock them.

The only times I do so are when they only run in-house adds. RoyalRoad is an example, they run advertisements for creators that use their platform, and its useful to find content you might enjoy.
Other than that though? Nothing. I have so many layers of add filtering that basically nothing gets through.

I disabled adblock for a forum I use. Some time after that, the owner independently decided to disable adverts for supporting members, so now it looks pretty much the same.

I never disable adblock unless the site isn't working properly.
- This is the way. But I won't disable ublock when the website tells me to or breaks intentionally.

I disable on 2 of my local news sites because they need every penny, but not on local news sites owned by major publishers.

I was thinking of disabling it for Ecosia.
They are committed to not exploiting my data and using profits for tree planting.

ArsTechnica
- Yes, and also Phoronix, LWN.net, GamingOnLinux, Hack-a-day, and a few others that give me good, content. It's the least I can do.

Sadly, the problem with SaaS and online software...: just cause it's great today doesn't mean it won't turn to shit in tomorrow. Blocking ads is just a small part of the kind of nefarious things that may be done.
So to answer your question, no.

I always end up disabling it on banking and .gov websites, just because I've run into issues where uBlock has broken those kinds of poorly made websites pretty often.

I do for creators I want to support. But I'll turn it back on right away if they're too annoying or sketchy.

Is there a way to set up patreon for any ad free website I browse?
Could my browser have some sort of cryptographically signed cookie that would let ad-free websites deduct 1-5 cents from my browsing account?
Website could check for the cookie before loading the ads?
Has this been tried?
