The opposite of a blocklist is an allow list that lets you permit trusted sources that already scan their content for CSAM. Lemmy and Reddit are nothing more than URL link aggregators that allow people to comment on content that gets shared unlike Mastodon that’s built on a web of trusted connections.
Gotcha yea no I really appreciate the input. I may share a blog to help admins in-general with the CSAM problem, at least share some thoughts. My other job is in cybersecurity. Constantly dealing with bad actors.
