That's true. That's why Textshell's proposal of leaving it up to the
server to decide what's duplicate and what not is the best way to go.
A simple implementation does no checking at all, whereas a very
complex implementation could use an algorithm to calculate similarness
of nicknames (taking into account the whole Unicode set and
spaces/dots/characters in between characters, ...), and reject the
ones that are too similar.
