I know about Hexbear and wanted to mention that it was a Hexbear user but this ironically happened just a moment after I made my own Hexbear account. I know some of the users there are extreme, particularly that user, but the community overall I find worth it.
That said I have to wonder what you mean when you say to avoid getting in trouble and to stay safe. Is there a history of people being harassed or harmed by those groups?
It’s a meme
