This bad buyer, buys items on ebay by winning auctions. He leaves the seller positive feedback, while at the same time leaving very low detailed seller ratings (DSR) of 1 or 2. This means you get positive feedback, but the 1 or 2 scores cause ebay to lower your search standing on ebay. This method is used by bad buyers to try to reduce future auction competition from other bidders by making the auctions less visible.
