Becasue most of the deals on ebay are dodgy, if a seller selling fake items and ebay making a lot of money out of him, they let him list his items despite negative feedback and compains. Ebay even removes negative feedback you left only because ebay makes money. There's a seller from HK selles fake watches for thousands of dollars, I have bought 2, returned them becasue they were fake, ebay removed my feedback in both cases.
