In my opinion, people who ask for specific behavioral rules to be published, are looking for an excuse to act like immature bullies by pushing said rules to the breaking point, or saying "well, you don't have a rule saying that I can't do such-and-such, or act like thus-and-so."
There are mechanisms in place to report a player who you think is behaving outside of accepted social standards. There's even the ability to not tune to the cesspool that is Channel 200.
