I was given a forum vacation once for making a joke about elves,which was linked by someone rephrasing what I said onto one of the Elf megathreads and they mass-reported me.
It was appealed and overturned within a day though. Mass reports can happen but it isn’t auto-suspension and I am skeptical about the existence of a secret forum cabal on Discord, or if there is there are several of them with some that hate me and others that don’t.
