Is Being In the Same BitTorrent "Swarm" Equal To "Interacting"?

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 emanated 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?"

The robbers in your first example committed the same crime under the same circumstances, they've acted as mutual facillitators, and evidence against one of them is pretty much going to amount to evidence against the other. So it makes sense to have a rule that that level of interaction can result in a joint case.

      For the bittorrenting, however, where the crime actually occurs is at the other end of a computer terminal, and those terminals are in very different places. You are probably not going to send a detective to the computer used by one defendant and find any evidence against the other defendant. The defendants don't know each other, and they haven't communicated with each other. You will have to present different cases to prove the identity of the person at the other end of the IP address--one might have a router and claim his friend was using his connection, another might have been at a coffee shop.

  7. another definition change by CheshireDragon · · Score: 2

    Here they go changing the definition of a word again. Their definition of interacting is now like my son(in 3rd grade) is interacting with some 6th grader. Even though my son and this other kid never saw each other, they are 'interacting' because they go to school in the same building.

    Probably a bad analogy, but I gave it a shot.

  8. Re:Swarm = Has file? by DanielRavenNest · · Score: 3, Informative

    No. When you download a magnet link from the Pirate Bay, or equivalent, all you have is a hash value, and possibly some tracker names. Somewhere on the network the .torrent file (which has checksums for the blocks and other metadata) is hosted by some other user. The hash value leads you connect with that user, if you have no tracker data, and you get the .torrent file delivered. At that point you don't have any part of the content files yet.

    Via one of the peering networks (DHT, Peer Exchange, etc) or a tracker (if this torrent has some) you can now announce your presence, make connections to others in the swarm, and start to ask for blocks. Once you have at least one block, you can start sending them to others. Sending to others is considered the illegal act, since you are making a copy.

    The peers you are connected to usually report how much of the files they have. If they have less than 100%, they are called leechers, and if they have 100% they are called seeders, but the protocol works the same for both. You just stop asking for new blocks once you have all of them. When you have part of the full set, you can be sending and getting blocks at the same time. That accounts for how popular swarms can grow quickly. As soon as you have one block, you can start passing it on, and a new swarm only has to send one full set from the original seeder to some number of other people, in pieces. Once a full set is "in the swarm", the original seeder can leave, and then the other people can swap pieces until everyone has the full set. That many-to-many swapping is what lets one seed become 10000 for a popular movie.

    (I'm sure others will correct me if any of the above is wrong)

    Well, courts would look at the intent. The intent of a clip with regards to fair use is to exist as a clip. If you go around gathering all the parts, your intent is to duplicate the full copyrighted work, and therefor is no longer fair use, even if all the parts taken individually are.
