The source is likely either due to the company themselves (and eBay protecting them) or competing sellers. I recently read selling fashion on eBay isn't for the faint of heart due to the other sellers-- leaving false bad feedback etc. I wouldn't doubt falsely accusing a competitor of selling fakes would be one of the tricks.

Also, no doubt the selling of forged brand name goods is legitimate problem eBay and the brand name companies have to deal with. Baseball card collectors know all about the market of fake baseball cards on eBay. Sports autograph dealers have gotten into trouble, not because the autographs were fake, but because the NFL jerseys the signatures on were knock offs.
