A piece of the lawsuit filed reads, "MediaSentry and the RIAA know that their investigations are illegal and flawed. MediaSentry is not licensed or registered to conduct private investigation of private US citizens. Moreover, in a March 2004 sworn deposition MediaSentry's then president admitted to various serious flaws in the investigative scheme which all Defendants know result in misidentification of individuals."
The lawsuit claims that not only are the RIAA's information gathering practices illegal and flawed, but the intimidating letters sent to the alleged provide a less than adequate 10 days in which to respond, giving the defendant not enough time to research the allegations or defend themselves. It has been cited that the RIAA uses its investigations as a campaign of threat and extortion, according to the suit.
