Wtf is this comment? So you either "turn the other cheek" and just let him harrass you, or else "you have to ruin his life and make him wish he was never born"?
You are right that OP doesn't have to "turn the other cheek" and does not have to put up with people's shit, but just because you should not turn yourself into a masochist that does not mean you should turn yourself into a sadist..
I have been running my own server for a few years now. I would describe it more as an alternative for What's App or Signal than an alternative to discord. I think it's more used in a professional/and or government setting for organisations who need to run their own services.

Yeah wtf was that comment and how is it upvoted? Sure, OP doesn't need to take shit and can fight back, but "ruining people's lifes"? Conspiring with other people to "make him wish he was never born"? Gerting him fired? How is that supposed to be useful? How does that solve anything?
