Well true it would appear as though something is amiss, however it's still firmly in the realm of speculation at this stage. "It looks like x, therefore it must be x". I prefer to keep an open mind on this, as you could say there is no firm evidence either way.

I'd rather not cause a witch hunt for speculative reasons at this stage, and for that reason the OP and others probably want to remove those pics because naming and shaming is against the forum rules. I know it was posted in good faith, but it's probably best to file a ticket and let a GM investigate whether the player is legit.
