It's completely possible there are people on Graal that are named Stefan. You can't just say Stefan Knorr is the only Stefan in the world. :P

Of course, if they are saying they are the Stefan that created Graal, then of course they should be punished. Birdbird's name is Stefan, but he doesn't run around saying "I'm Stefan I made Graal"

I think it's only serious when the person doing it is really trying to pretend to be Stefan in order to get people's account info, or mislead them, or something.
