Blocking Facebook as a user is not good enough. Any server that connects to them legitimizes them and is not acceptable behavior.
It absolute is not a conspiracy, and most people unwilling to participate in any server that interacts with Facebook in any way are doing so exactly because they understand the technology and Facebook’s history. Literally everything Facebook has ever touched turned to dogshit. “I won’t participate in a platform that doesn’t completely block Facebook” is not the naive, uninformed position. (That’s using Facebook and their other platforms.) It’s the people who recognize how pure fucking evil Facebook is.
