I, too, think the vulgarity feature is clearly a way to help regulate IC behavior/language and act accordingly when I am called upon to review a message. I've have recieved two in the past week or so from Swordfell I think.
However, I think both of those I chose befitting of a noble. You can insult people all you want, that's great. Just don't do it 1) with curse words, or 2) in a very 21st century internet flame fest manner.
