Has anyone defederated your instance? Introducing Defederation Investigator

defed.xyz Defederation Investigator for Lemmy

Discover who has defederated your Lemmy instance with the Defederation Investigator.

cross-posted from: https://lemmy.basedcount.com/post/113726

I couldn't find any tools to check this, so I built one myself.
This is a little site I built: the Defederation Investigator defed.xyz. With it, you can get a comprehensive view of which instances have blocked yours, as well as which ones you are federated with.
The tool is open source and available on GitHub. Hopefully someone will find it useful, enjoy.

You should probably cache results so users aren’tspamming other instances

- Never seen exploding-heads before, so I went to their page ... turns out they're leaving lemmy and the fediverse for nostr: https://exploding-heads.com/post/765290
  Main reason being all the "censorship" (ie defederation) they've received.
  
  Cool, it seems defederation works as intended!
  
  What is nostr?
- oh god is that a CP instance? How the fuck, is there no way to obliterate these people without going to their houses and [Redacted]?
- Oh wow, I just looked up Lemmygrad and was shocked and dissapointed at the results, seeing the Exploding Heads results changed that dissapointment to complete disgust.
- Didn't wanna be friends with those le redditors anyways
- Yeah, not really surprising. Radical left is usually shunned much more readily than the far right.
  
  Really says a lot about the liberals around us.

Since I was using this to write a little defederation thing on which instances find hexbear so repulsive they had to defederate I noticed the number from exploding-heads go up quite a bit from the 75 to 170 now. I will make it a point to call out two specific instances for being hilariously disgusting feddit.de aka the german federation, and feddit.dk both defederated hexbear but didn't defed the outright nazi instance exploding-heads earlier today, class act from the german and danish mod team.
Also apparently they were aware of it two months ago but didn't chose to act until today which yeah class act from the german admins. https://feddit.de/post/1151473?scrollToComments=true
- There's a cheap dark joke in there somewhere about Germans and Nazis
- Enlightened German centrism.
- As far as I can see, feddit has always had exploding-heads defedded? https://fba.ryona.agency/?reverse=feddit.de
- feddit.de blocks exploding heads.
  By and large feddit.de is to the left of /r/de which was already center-left.
  ...but whatever fits your narrative, I guess.

  obviously a mistake?

  You make a point that you have no idea what you are talking about but spread missinformation.

  The post you are referring to was a federated cross-post, besides that archive.org from 2 month ago proves you are wrong:
  https://web.archive.org/web/20230612194607/https://feddit.de/instances
- Exploding heads looks fucking dead lol why bother?

Looks like the usage may have gone over Vercel's usage policy (I'm not super familiar with Vercel)? I see the following when trying to bring it up:

402: PAYMENT_REQUIRED Code: DEPLOYMENT_DISABLED

That's very useful, thank you @Nerd02@lemmy.basedcount.com
Just to note if copying the URL you have to strip off the https:// or else it won't work (maybe people just don't copy that these days, but I ran in to that problem anyway).
- Uh yeah that is true. This was a one afternoon project, so I kinda threw the frontend together without thinking too much of it. I guess truncating the protocol instead of relying on the users doing it makes sense.
  
  Also: tested it on mobile. And my probe capitalized the first letter, returning an “instance not found”.

I couldn't find any tools to check this, so I built one myself.
Literally the first link on join-lemmy.org has a table showing all instances and it shows both how many instances that instance is blocking "and* how many other instances are blocking that instance
https://github.com/maltfield/awesome-lemmy-instances
- how many instances that instance is blocking "and* how many other instances are blocking that instance
  how's that helpful if you don't know which ones
- Very cool, ive been wondering about who defeds the most and now I know. Thanks.

ok, it seems to be working 😆
- even lemmynsfw defederated them, lol 🤣 why?
  
  For what it's worth hexbear wouldn't have federated with them anyway because the site is staunchly against hosting NSFW content.
  
  they are are extremely obnoxious mix of tankies and some other leftists who might have been slightly less obnoxious if they were on their own, but being in the group with said tankies, you don't want them any more than the former
  i apologize for grammar structure of my sentence and hope it makes some sense
  if you have few days of time to kill you can check this thread where lemm.ee admin is asking lemm.ee users about their opinion on defederating them. they brigade the thread in such a way they make more than 77% of the 2k comments in the thread (not exaggerating - the thread has 1920 comments when viewed from lemm.ee and 425 when viewed from lemmy.world which blocks them) and explain their philosophy in the process. so you will understand stuff like "who absolutely needs to be murdered for the crime of having more money than you in order to make world more just place & other tankies' wisdom".
  you have to acknowledge that they did really good job of introducing themselves, though - i had no idea they even existed the day before that thread and i am firm proponent of "defederate. now." today 😆
  
  No better boner killer than people spamming mao's dong.
  
  I normally hate the whole de-federation thing, but the radlib chapocels there are annoying af.
- there are a lot of <250 user instances on that list.
  They would probably never see their local content again

Thank you for this, @Nerd02@lemmy.basedcount.com
- Oh I forgot about this community. Thank you for spreading the word.
  
  You are welcome, thank you for your work!

Thanks, bookmarked!
Just linking a similar tool because I haven't seen it being mentioned yet: https://fba.ryona.agency/

  It's made by kiwifarms though, they even included their favorite word at the end of the page.
  
  It’s made by kiwifarms though
  I didn't know, thanks for letting me know. I frankly do not care though, in the exact same way that I do not care that Lemmy is made by tankies.
  The interesting bit would be how people with these extreme agencies abuse these tools or their users to further their goals.
  As I see it, both cases are questionable people providing useful tools free for me to use. Wether I use these tools or not, has what impact in regards to their agenda? I certainly would not like to be a pawn in their game, or support their cause without consent.
  If you think that's what happens, please show me. That would be very interesting to know and might lead to me ceasing usage / recommendation.

What I'd really like to have is a tool that lists blocked communities. That information is not as public as defederated instances.

6 instances have. Out of 1350ish.
A total of 29 users. Oh my.

aaaand it's down. worked this morning but now it fails with PAYMENT_REQUIRED

Neat tool!

any reason why sopuli.xyz isn't included?
- You can ask the creator (see the original post that I crossposted)

Wait why is “dubvee.org” defederated from my instance? Interesting…
- Ask them and report back.
  
  They don’t have any contact info, I guess I should PM from another instance.
  Its really strange since there is no porn, controversial opinions or else on the instance.

Looks like the only people not federated with the midwest are super small instances that aren't federated a big way with anyone.

It doesn't recognize kbin.social? Maybe I input the url incorrectly. Just curious
- Only works with Lemmy instances I think, I'm not sure what the technical reasons are.
  
  @Mane25
  No, it seems to work with my Mastodon instance - regarding Lemmy servers only. I just ttied https://defed.xyz/check/social.freetalklive.com It works spectacularly. :-)
  @Chetzemoka
  
  IF YOUR WAIFU WAS REAL SHE WOULDN'T LIKE YOU. :blobcatsipglare: YOU'RE A SUCKER. KILL YOURSELF, BECAUSE NO HITMAN SHOULD EVER HAVE THE DISPLEASURE OF INTERACTING WITH YOU. :uniinsane:.
- I think it only recognizes as "valid", lemmy instances. But kbin will be searched and it at least listed those instances federated with me.
- It says no instance found but specifically says Jengo hates you..
  I can see federated instances and 1 defederated even though it says no instance found (I think the tool is still case sensitive btw)

We got 10 detractors!

@Blaze Very cool! Thank-you.

Did this stop working?

Man... beehaw fucking sucks
- Why?
  
  Its an echochamber that defederated whit most instances, and they very good at gatekeeping since if you try to sign up in there they ask you for an esay to sign up like if they where hot shit and theres a 30% chance they acctually let you in, and the moderation in there is pretty ban heavy and the admins are pretty much reddit mods that love to keep their echochambers closed. So thats why.

Great tool! Thank you for creating and sharing it!

This won't be abused at all...
- Will it though? It's essentially public info already, and is a core part of how Lemmy works.
  
  Definitely, but I can see what the TC is saying. This tool simplifies the process even further for troll(s) who campaign against those trying to evade them.
- How can it be abused and to what end? You can go to any (instanceurl)/instances to see what it's federated to.
  
  A similar tool has existed for years and it is run by Kiwifarms with the primary purpose of ban evasion for trolling and harrassment campaigns.
  
  You get a list of the instances that have defederated from you, and you mount a coordinated attack against them
  
  On mastodon, in my circles at least, it's taboo to link to the equivalent for mastodon. It makes any harassment campaigning, trolling and re-routing much easier. Unless you're willing to build the tool yourself, you just don't really know these numbers. Once you use the tool (and I have seen and used it), you see very easily who the big defederators etc are.
  I'm going to bet that this tool is not worth what ever value or curiosity it provides. It so easily puts targets on instances backs, including smaller instances that are probably easy targets.
