I reported a more sinister one last night. A guy had hijacked some guy's account with 700+ positive feedback (apparently all for selling records) and listed 4 or 5 one day auctions for MF Kodak DCS pro digital backs. 1000 dollars buy it now (only no buy it now option). Instructions to email him at an address in the auction, not through ebay.
It is really sad because people come to ebay and see a "too good to be true" price by a guy with a 99.9% rating and over 700 feedback and they just take it hook line and sinker. Ebay is such a great resource, but you really really need to be careful.
