This wouldn't be the first time that the Prosper site's content has been copied by an unrelated website (assuming that is what happened here).
Shortly after it launched, Prosper successfully sued a company in federal court for copying its content and posting an identical website. And our old friends at FAN had a site in development that copied Prosper.com content, but with a half-assed search-and-replace job to change the name of the company from PMI to whatever name FAN was using for that project. However, it still listed Prosper's address as the FAN front's location, and Giedgowd as its compliance officer. The site went down shortly after Prosper gave FAN the boot.
