Actually I have serious questions about the validity of the methods used by myspace.

OK. I can agree with that.

I happen to have a very common name in real life.

I've dealt with that problem myself. I toyed with the idea of changing my name for seven years before doing it. The catalyst was being mistaken for someone else which nearly caused legal problems.

one of the biggest, most hysterical taboos of our culture.

Oh certainly. Someone in my parent's hometown got out of jail in two years for first degree murder (was crazy, but feels much better now). Yet this issue they follow you for life more than anything else.
