I know what you're saying, but I get very strange bidding patterns on my auctions often, not 0 bidders as I have them blocked, but low score bidders often bid in strange ways, like bids in several increments of £1 etc. It's easy to look at the way an item gets bid on and think the seller is shill bidding, but it's not always the case
The same with the price too, I get items end much higher than expected, along with items which make much less than expected, eBay can be a strange place sometimes.
