According to Assistant U.S. Attorneys, the Indictment alleges that the defendants created more than 40 User IDs on eBay using false registration information, and then used those aliases to place fraudulent bids to artificially inflate the prices of literally hundreds of paintings they auctioned on eBay from November 1998 to June 2000.According to the Indictment, the defendants shielded their true identities from eBay by providing bogus names, postal addresses, and telephone information, and by providing e-mail addresses obtained from free e-mail providers known to collect little or no verifiable information on their account holders. By creating multiple User IDs, the defendants intended to trick other eBay users into believing that the "shill" bids they placed on each other’s items were legitimate.
“I do most of my work for a few builders that I have known for years. My estimates of what it will cost to do a job for one of them come out about right.
