A vandal discovered today that if your username starts with "WP:", as in "User:WP:ANI" then attempting to block the account results in a block against User:ANI instead of User:WP:ANI.

I'm not sure what part of the WP: magic is triggering this problem, but it could become a significant nuisance if more people pick up on it.

The workaround is to rename the account first and then block it.
