Is This A Shill?

Check the bidding history. 1) Is the cancelled high bid absurdly high? Is it from a low/no feedback? (eBay no longer lets you know other bidders identities) It is not uncommon for a shill to place a single VERY high bid, in order to reveal the full amount of the highest bid. Another use for a shill is to bid credible bids to auction-up the price. That sometimes backfires when the highest legit bidder gives up, and the shill ends up winning. 2) How far below yours is the next one below yours? (Is "and somebody else is interested" credible? or is that just to push you into a quick decision?) Cancelled because he is a "SPAMMER" is not credible reason. "scammer" might be, although certainly seller's wording, not the wording that eBay would use.
