There have been users spamming CSAM content in !lemmyshitpost@lemmy.world causing it to federate to other instances. If your instance is subscribed to this community, you should take action to rectify it immediately. I recommend performing a hard delete via command line on the server.

I deleted every image from the past 24 hours personally, using the following command: sudo find /srv/lemmy/example.com/volumes/pictrs/files -type f -ctime -1 -exec shred {} \;

Note: Your local jurisdiction may impose a duty to report or other obligations. Check with these, but always prioritize ensuring that the content does not continue to be served.

Update

Apparently the Lemmy Shitpost community is shut down as of now.

As far as I know, images should not be federating to federated instances, right? Image proxying is supposed to be added to pictrs version 0.5.0 but it is still in alpha.

Images do sometimes. At least in my instance they do. See this post for example. There's a local copy stored in my server.

edit: I'm running pict-rs 0.4.2

I get it. Thumbnails are cached. Thanks.

[-] hitagi@ani.social 6 points 1 year ago

Not just the thumbnail. The full image is cached. There's a PR request to disable thumbnail caching but not the full image.
