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.

I went ahead and just deleted my entire pictrs cache and will definitely disable caching other servers images when it becomes available.

Anyone know if this work is tracked anywhere? I’m suddenly really suspicious of continuing to run my own instance.

It does say "thumbnails" but as far as I know, Lemmy (or pictrs) makes a copy of the full image too. I don't know if this PR includes full images.
