NewYorkCountryLawyer writes: "In the new wave of bittorrent downloading cases, the plaintiffs' lawyers like to lump a number of "John Does" together in the same case in order to avoid filing fees ($350 a pop). Their excuse for 'joinder' is the allegation that the defendants 'interacted' with each other by reason of the fact that their torrents may have eminated from the same "swarm". In Malibu Media v. Does 1-5, when John Doe #4 indicated his intention to move for severance, the Court asked the lawyers to address the "swarm" issue in their papers. So when John Doe #4 filed his or her motion to quash, sever, and dismiss, he filed a detailed memorandum of law (PDF) analyzing the "swarm" theory in detail. What do you think?"
