I won't go into full detail since it's a lemmy admin thing but someone in a community on another instance posted genuine CSAM today and it got federated across different instances. It was originally just one, but I was informed it was multiple.

This is an ongoing issue that is a topic of major discussion amongst lemmy admins. Please be advised that there is info regarding this that cannot be publicly shared at this time, but know that it is being handled carefully in a coordinated manner.

I'm sorry if I take a step back from posting for the next few days.

Newly federated posts should work as intended.
