Citadel Security Software v Does 1-5 [1]

Citadel Security Software (CDSS), a company that provides "enterprise vulnerability management solutions," sued five "John Doe" defendants who criticized CDSS on a Yahoo! Finance message board focused to the company. On March 16, 2005, CDSS sued the five anonymous posters for defamation and business disparagement and subpoenaed Yahoo! to get the identity of the posters.

On April 4, 2005, one of the users of the message board, "onlymybusiness99," filed a motion to quash the subpoena [2].  In his motion he argued that there is neither allegation nor evidence that the speakers committed any legal wrong, and because in any event the case was improperly filed in Texas against and he or she lives in Minnesota.

On May 3, 2005, CDSS voluntarily dismissed it's claims against "onlymybusiness99" before the court had a chance to issue a decision on the motion to quash.

As of October 17, 2008, there has been no further action in the case.
