Some shitheads started to spam CSAM and it got cached on other instances too. db0 admin created a tool to check every upload via library of hashes of known dangerous images (not images themselves). Since then, most images are stored locally on instances and aren’t cached by others.
Comment on They fucking geoblocked blahaj.zone

So now if i want to see a post by a user on blahaj, i have to turn on my VPN just to see it. Fuck this place. 🙄
One of the first conversations I was on when I joined was one between Ada, the lemmy.blahaj.zone admin, and some guy in a Middle Eastern country. Apparently his country had blocked lemmy.blahaj.zone at the national network level.
The Threadiverse is federated, so one could view posts from lemmy.blahaj.zone elsewhere, but not images, which did not propagate.
I thought that at some point, lemmy servers had started also storing images, but upon checking, it looks like they have not. I did run into one – no longer up – that had, according to the description, had apparently been modified to do this, probably to afford its users more privacy. In theory, if you could find one that did so, you could just rely on propagation through the network.

That’s not what my tool is doing

That’s good to know, thank you. Unfortunately alot of the communities i spend time in have a lot of blahaj users, so i don’t have context of the post sometimes. Better than nothing, though.

If i remember correctly after the downfall of reddit and the mass migration to Lemmy happened a big issue was CSAM spreading across the Lemmy servers. Wouldn’t surprise me that that is the cause that images are no liner stored across servers.
