Hehe, I'm in that screenshot
(You can see "*FxChiP" which is short for "*FxChiP (Baddies)")
Anyway...
Yeah, that screenshot could be easily faked. But then again, so can
any screenshot ever made or taken.
RC users cannot have or create profiles. If you see an "RC" icon with a profile, it's actually a player with the RC/judge head (you can even get them at Harmonia!). And if the player has "-off duty-" or something like that in his name, has a profile, and appears to be on RC, check for a profile. If there is one, you know at least he doesn't have an RC. He might be staff otherwise wearing a judge head, though....
