If his account hasn't already been taken down, someone should seriously report his ass.
It's nothing new with an engine like ebay unfortunately, and I for one would never purchace any form of award or signature from such a site. I've been lucky enough to get autographs from Ron and Duff in person, and I feel that this is the only way you ever
really know that something is authentic.
I remember back in like 2005, I used to drool over the signatures on ebay, thinking how cool it would be to have them. But now I know
BETTER (pun intended), as I now realise that maybe 98% of those signatures were big fat fakes.
