The RIAA is confident that this "sue em all" tactic is working and is slowing down file-sharing. However, latest studies have indicated that the RIAA's tactics have not effected P2P use overall, but that P2P use is growing at a huge rate. In order to issue a subpoena against the user's ISP, the RIAA first must gather evidence of the user's P2P activity. They can then retrieve the identity of user from the IP address that was being used for infringement from the ISP. In some cases in the U.S. the RIAA have to file a "john doe" lawsuit against the defendant before they will even learn the true identity of the user.
