We have a very simple means on our hands to enforce it: revert every single edit Cumguzzler makes.
To remove information from the Wikipedia because of who contributed it, rather than because of the nature of the information itself, would be to cut off one's nose to spite one's face. I haven't been paying much attention to this person's edits, but other people have stated on the person's User talk page that they have made useful contributions. If I recall the earlier case of Throbbing Monster Cock correctly, a developer just changed his name to "TMC", and there were no further problems. Couldn't the same thing be done again?
