User blog:Sourthumb/Hashtag in a username?

Sooo I was just checking the popular games and I stumbled across Dynamic Flight Simulator, which was owned by reset#2164240. I KNOW his name was simcityweegee before. I checked his profile and there was no question mark that said he changed his name. I think it is copyright for "simcity" but you can't really know. I don't think he hacked either.
