Interesting bidding


Recommended Posts

Oddly enough I've got my Estate car on ebay at the moment and a bidder has come along and bid the car up in the silliest small increments possible and as of today I have something like 80 bids with 95% of the bids coming from this one guy! I know for a fact that to the wary buyer this will look like shill bidding and I am wondering whether the bidder has deliberately/strategically done this to put others off by making it appear like shill bidding... I've hence contacted the guy and asked if he wants to view the car to be sure it is worth further bids ( :) ), however he has said that he lives in Birmingham and he's happy to wait till the auction ends before driving to Northumberland for the car! :)

I sense he may let you down if he's the winning bid. :)

I don't understand the shill bidding detection algorithm you're all using. Why is bidding up in small increments any better than putting in one bid for the minimum amount you're prepared to accept? Especially as it just draws attention to what you're doing, if you are a shill.

Basically a shill bidder doesn't want to win the auction so they'll regularly just stick bids in of small increments hoping to goad more bids from other interested parties. As to sticking in one bid; a shill bid can be done this way especially if the seller has an absolute minimum they want for an item and aren't prepared to gamble with selling it cheap. The little and often shill is intended to draw in regular bids from other ebay users who don't do the one set bid in the last seconds/minutes!

if there are other bidders... I'd feel very tempted to cancel his bids and block him from bidding. His behaviour says "I'm a difficult buyer" to me...

I was contemplating that but in the end I sold the car locally and ended the listing. :)

Why? If someone inexperienced is bidding, they might not understand the concept of someone else having put in a large bid. To them, it will appear that they're in a bidding war as the other person's bid keeps increasing.

I find it perhaps excessively cynical that every time an odd bidding pattern occurs, the immediate response is that it must be shilling. Why, if someone were to sell two identical items using the same photo, one after the other, I suspect there would be some who would be cynical enough to start crying foul.

Because [b]A )[/b] most of these cheats aren't very bright and with great regularity open up new accounts to scam people with. And [b]B ) [/b]You can never be too careful where money's concerned, so a little suspicion posted in an ebay related subforum is fine, if only to get others Spidie senses tingling. I'm not claiming to be clairvoyant just prudent. :)
