BattleMaster has always been very much PG-13, at least.
Expecting people not to use words like that in the game and the community around it "for the chiiiiiildren" is not really a particularly helpful attitude.
I don't have a problem with the word '!@#$%^&' per se, or with swear words in general, but "Don't be an !@#$%^&" is an !@#$%^& thing to say.
those 4 rules are good. the don't be an !@#$%^& is really good. The reason why is make sure people know that the forums are being watched and the tolerance level will be low. Its a strong statement and that is what is most important.
I really don't get this supposed need for more authoritarian controls. According to Tom, only 2 or 3 postings per month get reported. Personally I've never felt the need to report anything. Yes, sometimes people are bitchy and sarcastic and combative and unpleasant. Get over it.
