I don’t know if you need this info, but I was pretty disturbed to see unexpected child pornography on a casual community. Thankfully it didn’t take place on SLRPNK.net directly, but if anyone has any advice besides leaving the community in question, let me know. And I wanted to sound an alarm to make sure we have measures in place to guard against this.
This is probably the best option; in a world where people use ML tools to generate CSAM, you can’t depend on visual hashes of known-problematic images anymore.
