"Your username has been blocked indefinitely because it may be rude or inflammatory, unnecessarily long/confusing, too similar to an existing user, contains the name of an organization or website, uses non-Latin characters, or is otherwise inappropriate (see our blocking and username policies for more information)." http://en.wikipedia.org/w/index.php?title=User:%21%21&oldid=95783799
