3.3 Profanity and Offensive Language. You may not use profanity or any language that a reasonable person would find offensive. The Game is for players aged 13 and older. You agree to behave accordingly.
OP, just take a snapshot of your Alliance window, and the Chat Log next time. Leave + report, and let the GMs sort the rest out. If it's true what people say that they can get warned for bad language quite easily, then take advantage of that and don't fall for their bait. Eventually you will find a group that either treats fellow players with respect, or at least doesn't talk much at all.
