Can anything be done about this guy?

I called him out on his fake watches and his bad box. Now he's blocked me, removed my comments and removed ratings from the video (there were a LOT of negative ones). Though his mail to me is amusing (he called me a f**king a**hole) I feel bad for anyone who might be foolish enough to wire money to his paypal account. I'm assuming ebay has bounced his crap, courtesy of you good people. Is there anything that can be done on youtube? I told him I hope anyone silly enough to wire him anything has the connections to nail his ass for fraud.
