I personally wouldn't ban them unless they were actively making it difficult and unenjoyable for other users. I don't mind laughing a bit at a disparaging message, but I have a thicker skin than most. However, what I wouldn't mind doing for the really abusive is grabbing a beer and cooking up something that makes them feel abashed. A personal homepage for their account with something like 'do unto others as you would have them do unto you' plastered across the top. Man, maybe even make the banner randomly draw from a list of trite sayings...'Consideration for others is an important virtue'. We get a few rough emails/suggestions come through, but haven't had to deal with anything profane. Usually it's something like "This site is terrible, it doesn't work worth crap and I can't believe you have any users". It's almost always something really hilarious that causes it (javascript being turned off, they are using IE6). I respond with an explanation, query for more and try to help. Everytime the person turns their attitude around and says thanks, that we have good service. I am sure that will change when our userbase grows, but it is working well so far. On a sort of related note, I did have a user put in a name of F YOU (but fully spelled out, yes all in caps). Best part is they were an active and seemingly happy member. I am not for censorship, however, we are currently a small site, so his name might come up semi-often for other users. Enough to drive down the value for other users, which is when I draw the line. I decided to change it to LOVE YOU. It's still there, even though the person has used the site many times since I made the change. They must have a good sense of humour :)
