I been looking for this too since some time, there's people that change name to some symbols just to annoy others (and admins, since it gets harder for them to tag those players, and not all admins know about the !status and find the #number) , and i always thought of changing their name to something that gets stored on a database and also they can't change, so everytime they join the server, he'll same the same nickname (but more important, he won't be able to change it)
