There have been users spamming CSAM content in [email protected] 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 {} \;

I’m not surprised. It was quite common for shitheads on reddit to make an account, post a few comments on /r/againsthatesubreddits, then post CP on other subreddits to spin the narrative that AHS was trying to shut down hate subs.
