As for Ceglia, Zuckerberg said in a sworn statement that the two did have talks and did sign a contract. However, this contract was not for Facebook--it was for Ceglia's startup website, called StreetFax. The two sent some 175 e-mails back and forth, but Facebook was never mentioned once, the company said in its filing.

The filing also mentions Ceglia's alleged involvement in property and wood pellet scams in an obvious attempt to portray the man in a negative light in front of the courts. "The fact that Ceglia has spent the past seven years as a hustler ... further highlights the fraudulent nature of his claims in this case," it said.
