the subject is shield bidding not shill bidding. Its easy to spot shield
bidding. Its the guy that posits a ridiculously high bid and cancels it
in the last minute.
solution is simple-- Ebay ought to bar all bid retractions. Why would
anyone ever really need to retract a bid anyway? "mistake?" nonsense. If
anyone ever retracts a bid on one of our items for any reason-- their
name goes right to our block list.
