Ignore certain users option
Sometimes I really wish I could ignore questions from a certain user, much the same way that I can ignore a certain tag.
There are users that keep posting "please fix my code, can't see what's wrong" questions all day long, and they don't seem to learn anything.
The questions do not rise in quality at all, and it starts to annoy me to have accidentally clicked on one of them, because answering would be pointless.
I know it's harsh and all, but as the popularity of SO rises, I expect this type of user to become more frequent. An "ignore user" option is not too unusual for social sites, I guess.
