Can someone find a pic of the guy?
As I mentioned earlier Jon is far from anonymous. I personally managed to find a few somewhat blurry and old(2002) pictures of Jon.
Including one where Jon has a cat on his head

He even confirmed it was him on IRC.
Wouldn't Ken get in big trouble if Ukyo indeed has a legit story? (well in any way actually. I don't think it is allowed to steal from even a scammer..)
