Bid Shielding "Scam"



> The author of the "Scam" story just wrote me back. Thought I > would share it with you. It's rather long....

> > I did over-simplify the technique for clarity, > but it is real. Here are more details -- I hope this helps.

> > 1) you place a max bid for the item - Say the item is an antique vase. > You like it, think its worth $100. Bidding opens at $2, with increases > of $5. You place a bid of $100. eBay gives you the opening bid at $2. > You are protected up to $100.

> > 2) another bidder Bidder 2 comes along and he wants the vase for > $50., so he bids that amount. Bidder 1 is still the high bidder, at $55 > ($50 + $5 increment). So Bidder 2 comes back and bids again, this time > at $105. Viola! Bidder 3 is now winning at $105 (he met your high bid of > $100 + the $5 increment.

> > 3) more bids Bidder 3 thinks the vase is worth $125, and bids that > amount. He becomes high bidder with a price of $110. Bidder 4 thinks the > vase is worth $130, and becomes high bidder posting that amount. The > auction continues in this way until the end. Usually, in the last > minutes, the bidding gets very heated, and the vase may end up selling > for $600., which is close to what your local antique shop might charge.

> > This is how the scam works:

> > 1) Same vase, opens at $2. Only this time, Bidder 1 bids $1000. The > opening bid still shows only $2. He immediately follows with a false > identity Bidder 2, at $990. Bidder 1 becomes high bidder at $995. Since > this is more than you can get a similar product locally, and in a price > range the average user is not going to spend lightly, there are no other > bidders.

> > 2) Scam complete. 15 seconds before the auction ends, Bidder 2 > rescinds his bid, the "high" price drops back to the opening bid of $2, > and Bidder 1 wins at that amount. Unless the seller has a substantial > reserve to protect his investment (which is discouraged by eBay) he will > be obligated to sell the vase for $2. If he does have a reserve, he > doesn't have to sell, but he still owes eBay posting fees and the > auction was a waste for him."
