I have the red bike in my sig on ebay, & have gotten a few bids. A guy just asked me if I had the original receipt, so he could claim to be the original owner &(illicitly)qualify for the warranty. 
I have no intentions of doing this or even indirectly facillitating it, but I'm interested in my TB brothers' thoughts on the matter- what would you do? Specifically, how would you politley & professionally explain to this person that there's no stinkin' way?
