I'm confused by the structure of the article which is just a bunch of interleaved posts from social media, is there actual illegal content being bought and sold or is it animations? If it's the latter it's reprehensible and arguably cover for real CSAM - but it's not illegal in the US. It's (currently) protected speech because of the Ashcroft v Free Speech Coalition SCOTUS ruling. If it's the former, holy shit. I can't believe it's just the security team responsible. And another thing that's not clear, was it them that was responsible for the content, or were they fired for speaking up?
