If he wanted to win the auction then obviously he was willing to pay BTC63, no? He's still not forcing anybody to pay money they would not be willing to pay. This is equivalent to refusing a price in a bargain, something perfectly reasonable.
I don't see any problem in what Garr did, however I am disappointed he didn't warn people he was doing this. However, that's still not something worthy of a scammer tag.
Right, except they weren't bargaining. They were in a binding auction, and last time I checked, an auction doesn't automatically get advanced to the maximum amount that a bidder is "willing to pay".
bargain that functions rather like an auction would you agree that what he did isn't morally incorrect?
