That style of text is called "Zalgo text." It comes from a series of online horror stories about a Cthulu-esque creature called Zalgo, a malignant entity with the power to destroy the world.
In the stories, Zalgo's name is always displayed with those weird diacritics.

Nice touch! (A bit obscure, though.)
How did you insert the diacritics? I'd never have guessed that UBB.threads could display them.
Edit: OK, I see that there's a Zalgo Text Generator, but I'm still surprised that the Forum software can render it.
