Anyone else noticed you can not use "PS3" in your PSN Account username? I tried registering a few names and any time PS3 was in the username it was blocked and I was told the username cannot be used. Kind of odd....

Perhaps they have administrators that use "PS3" as a title or a suffix...

Yeah maybe what Negasie said. Or maybe they are preventing only YOU from using it and everyone else can, muahahahaaaa.

Well it was really annoying. I was trying to register ps3court as a PSN ID

i was thinking about that a while ago, like if somebody was lucky enough to get the name "PS3"....but i guess not
