What motivation does ebay REALLY have to stop shill bidding.... anything that drives the price up adds to their bottom line.
Absolutely! It's why eBay is always filling us with hints like, "Bid soon, so you don't lose this item." The fact is, bidding soon is the BEST way to lose an item! But it does one thing very well: it drives up the price. Bidding late (VERY late... like seconds before the end), not only increases the odds that you'll snag the item, but keeps the price low, since no one has time to submit repeated nickel-and-dime bids until they find one that tops yours. But we all know that already, right?
And I agree with everyone who's talked about multiple bids placed in the middle of an auction. Occasionally it's shill bidding, but mostly It's just newbies who don't understand the system and keep inreasing their bid to a point where they think it's high enough to keep others bidders from topping it. Dumb because a) it doesn't work, and b) it increases the final price for the winning bidder, whoever it is.
