Extract:
Online auctioneers smell a rat.
Individuals who sell items over online auction sites like eBay
<http://www.ebay.com/> and AuctionUniverse <http://www.auctionuniverse.com/>
suspect that their bidding sessions are being artificially manipulated by
phantom buyers known as "shielders" and "shills"--and that the auction
sites
are not doing all they can to discourage the fraud.
