discouraging the dick

One of the most requested changes to my game would let users edit the name of their spaceship. When I finally added that, they immediately named their ships “dickbutt69” or something similar. I recognize that this is part of the larger axiom, that if you give game players a creative tool (even a text entry widget) they will immediately make something obscene.

But it annoys me, and I have anecdotal evidence that it harms the game ecosphere at least a bit. So now that we’ve all acknowledged that this behavior is innate, I’d still like to explore ways to minimize and discourage it.
