[sdiy] ebay internal shill bidding?

[David Bulog]

the best auction system Ive seen is Trade Me (its bigger than Ebay in NZ) ----to avoid bid snipe --the auctions will auto extend for 2 minutes if any bids are placed in the two minute window---its possible for an auction to run 15 minutes over the end if genuine bidders compete against each other

I hadn't heard of any bad interactions...most of those happen between buyers and sellers of course when one doesn't do what they're supposed to.   There used to be communication between people in the ebay community.  They totally killed that pretty much.

> Ok the auction is ending at 12:16 let's say.  Cecil scratches his head and ...while knowing he can get a similar spatula at spatula city for only 12.99... has basic human territorial behavior.  And he decides John has no right to this because it's HIS spatula in his way of thinking. IT's just a matter of PRINCIPLE now.  There is no money limit.   So Cecil manages to slam down another bit at 12:15:49 of 22.00 but...he receives a disappointing note that he must enter another bid because John's ceiling happened to be 22.00 and since John already had that as his bid, Cecil can't win with the same bid since John was first.

> While cecil is frantically trying to figure how to up his bid 5 bucks in 10 seconds... HORATIO who knew the tendencies of humans to have territorial behavior had cleverly held his bid to the end.  Unfortunately he didn't know that he could get this spatula at spatula city for much less and he had put 25.50 on cue to be dropped at 8 seconds before the end of auction.  SAM though also unaware of those great deals at spatula city put down 26.00!  Sam's snipe, however, didn't land on ebay until 5 seconds before the end.
