eBay's fraud protection includes a feedback system that allows

users to praise buyers and sellers--or criticize how they

handled their transactions. But victims said the feedback

mechanism failed because the seller had established a good

reputation on the site.

eBay spokesman Kevin Pursglove confirmed that some of the

positive feedback seemed to be fraudulent.

"There were a couple cases of shill feedback," he said. "That's

cause for immediate suspension from eBay."
