<p>A method for selectively allowing participation in an auction, implemented at one or more servers, includes steps for receiving a request to participate in the auction, receiving machine fingerprint data related to the request to participate in the auction, saving the machine fingerprint data in a memory, comparing the machine fingerprint data with previously stored machine fingerprint data, and determining, using the machine fingerprint data, whether to allow the participation in the auction.
