It IS a scam. It's shill bidding, in other words fraud. And no marketplace can condone fraud. In the financial world that should qualify as stock manipulation or insider trading or something like that. This is not a good comparison, seating diners by the window would be more like a featured listing on the home page of Sedo.com. A shill bid is when the restaurant jacks up the price of the menu while you've begun to eat. That kind of "slightly deceptive" game is also a sure way to get banned from NP and other forums. Yes, people shouldn't place bids like lemmings but two wrongs don't make a right. The purpose of shill bidding is not just to "start the ball rolling" or make the domain look more attractive - often it is a way of artificially driving prices up at the expense of legit bidders.
