This is literally why I joined Lemmy :) I got banned, not for advocating violence or racism but for calling out a mod for removing posts that were not breaching any rules.
Initially it was a 3 day ban, I appealed it and they turned into a permanent one lmao.
Yeah, bans for hate speech etc. are perfectly understandable but being banned for stepping on someone’s toes is pathetic.
It’s also the fact you can’t really appeal it that irks me, they just say they looked at it and will uphold the ban without further comment.
