We recently had a flat-earther. I was tolerant of this up until the point he got aggressive in private messages when asked about if he is a STEM student or professional. So the situation mostly resolved itself, he is no longer with us.

With that said how should we handle people who are otherwise respectful but post almost 100% flat-earth content (basically people who are explicitly anti-STEM)?

@snow I dont consider it ethical to sharing private messages, its a right to privacy thing. With that said, even if i wanted to, I cant, since the account no longer exists neither does the content.
