The GMs in this game are terrible and will give you warnings/bans for whatever they feel like even if what you did was so insignificant no normal person would report you over. If you never want to see it again I suggest never talking in any public or party chat again unless it's o/ or gg, there's a reason why everyone's nice in game but outside of it it's way different.

As you can see from the miserable losers in this thread no one will believe you if you say you were warned/banned for nothing because they haven't had it happen to them yet so don't bother trying to justify it to randoms.
