This is simple....Vulgar language is not tolerated, period.
If you choose to type out a swear word in shout, talk, party, whisper or tell to anyone in an attacking fashion, the DM reserves the right to boot/ban the guilty player without any further discussion. Obviously, if the game is getting anyone that upset they need to remove themselves from the source of frustration.
