Hello everyone,
We unfortunately have to close the !lemmyshitpost community for the time being. We have been fighting the CSAM (Child Sexual Assault Material) posts all day but there is nothing we can do because they will just post from another instance since we changed our registration policy.
We keep working on a solution, we have a few things in the works but that won’t help us now.
Thank you for your understanding and apologies to our users, moderators and admins of other instances who had to deal with this.
Edit: @Striker@lemmy.world the moderator of the affected community made a post apologizing for what happened. But this could not be stopped even with 10 moderators. And if it wasn’t his community it would have been another one. And it is clear this could happen on any instance.
But we will not give up. We are lucky to have a very dedicated team and we can hopefully make an announcement about what’s next very soon.
Edit 2: removed that bit about the moderator tools. That came out a bit harsher than how we meant it. It’s been a long day and having to deal with this kind of stuff got some of us a bit salty to say the least. Remember we also had to deal with people posting scat not too long ago so this isn’t the first time we felt helpless. Anyway, I hope we can announce something more positive soon.
Good question. Yes. Also artefacts from compression can fuck it up. However hash comparison returns percentage of match. If match is good enough, it is CSAM. Davai ban. There is bigger issue however for developers of Lemmy, I assume. It is a philosophical pizdec. It is that if we elect to use PhotoDNA and CSAI Match, Lemmy is now at the whims of Microsoft and Google respectively.
Honestly I’d rather that than see shit like this any day.
The bigger thing is that hash detection tools don’t want to give access to just anyone, and just anyone can run a Lemmy instance. The concern is that you’re effectively giving the CSAM people a way to know if they’ll be detected.
Perhaps they can allow some of the biggest Lemmy instances to use the tech, but I wouldn’t expect it to be available to everyone.
Facebook and Reddit don’t have local CSAM detection but rather use Google’s APIs.
This isn’t something that any average user can get access to. Even the largest Lemmy instances are small compared to Reddit and Facebook… and they don’t have local testing either.
Part of this is also a “this isn’t just detecting and blocking but also automated reporting”.
Furthermore, Lemmy is AGPL, and providing a Lemmy instance with an implementation that would run the risk that it wouldn’t be able to remain closed source (AGPL license violation).
Mod tools are not Lemmy. Give admins and mods an option. Even a paid one. Hell. Admins of Lemmy.world could have us donate extra to cover costs of api services.
I agree. Perhaps what Lemmy developers can do is they can put slot for generic middleware before whatever the POST request is in Lemmy API for uploading content? This way, owner of instance can choose to put whatever middleware for CSAM they want. This way, we are not dependent on developers of Lemmy for solution to pedo problem.
