"The number one reason buyers cited for decreasing or ceasing their activity on eBay was negative unwarranted retaliatory feedback they received from sellers. It's cited as a bigger problem than even not receiving shipment," said Ebay spokesperson Usher Lieberman.

Or if you give genuine negative feedback to a dodgy trader, they will negative you as well which isn't fair.
