Duffin v. Does [1]

Cyd Duffin, principal of Colony High School in Palmer, Alaska sued MySpace, Inc. and John Doe defendants for defamation and invasion of privacy over the posting of a fake MySpace profile, which falsely depicted her "as a drug-using racist with a sexually transmitted disease who insults disabled students and likes books about pornography, anarchy and the Ku Klux Klan," according to the Anchorage Daily News [2].  The Anchorage Daily News also reported [2] that Duffin dismissed MySpace from the case after the company agreed to cooperate by turning over records related to the creation of the fake profile.  

UPDATE:

7/14/2009 - Duffin dismissed the suit [3] after two students confessed to authoring the fake profile. Though the two students were punished, Duffin did not disclose the severity of their punishment.
