From what I can see, Direwoof, it looks like your messaging specifically mentioned excluding some realms in a fairly insulting manner. It wasn’t mass reported and it doesn’t look like it was for “no reason”.
You are welcome to decline anyone you wish for whatever reason you want. Advertising your bias in your message may be a bit unwise though. “Abusive chat” doesn’t have to be inappropriate/vulgar language. You can be fairly insulting without ever using that kind of language.
If you wish to have the matter reviewed you will want to submit an appeal.
