What Is Torrent Piracy?
Torrent piracy spreads files between users' own devices, coordinated by torrent files, magnet links, trackers and the DHT. Indexes, trackers and peers are separate targets and each needs different action.
Definition
Torrent piracy is the unauthorised sharing of copyrighted files through BitTorrent or another peer-to-peer distribution system.
BitTorrent splits a file into pieces and lets every downloader share the pieces they already have with others. No single server holds the file. The protocol itself is lawful and is used by legitimate distributors. Torrent piracy is its use to share films, series, music, books, games and software without permission.
The moving parts behind a pirated torrent
Pirated content passes through several distinct components. A torrent file or a magnet link describes the content and how to find it, but contains none of the content itself. Index sites list torrents with titles, descriptions and comments, and are how most users find material. Trackers, and the distributed hash table that works alongside them, help peers find each other. The swarm is the set of peers actually exchanging pieces. Seedboxes, rented servers set up for torrenting, are often where the first copies of a release are seeded.
Indexes, trackers and peers need different action
Because the content lives on users' devices, there is no single file to take down. Index sites can be sent notices to remove listings, and search engines can be asked to delist index pages. Hosting providers and domain registrars become relevant when an index ignores notices. Trackers can be asked to stop tracking a specific info hash. Peers can be observed by IP address while they share, and in some jurisdictions rights holders or their agents send notices to internet providers, which forward them to subscribers. Whether that route exists, and under what privacy rules, depends heavily on the country.
Why a torrent download is also an upload
Torrent piracy is download piracy: the user ends up with a complete local copy. While downloading, the client normally uploads pieces to other peers at the same time. That matters legally, because the user is distributing as well as copying. Streaming piracy works differently, since viewers watch without keeping a file and without passing pieces on. The contrast shapes both the evidence and the targets, as set out in streaming piracy vs download piracy.
Confirming what a torrent contains
Analysts verify that a torrent actually contains the claimed title, because fake and mislabelled torrents are common. Useful evidence includes the info hash, the file list and sizes, the release name, and downloaded pieces checked against the original work. A capture of the swarm at a given time shows the file was being actively shared. Notices to index sites should identify each torrent page precisely. A notice that names only the title leaves the site room to say it could not find the material.
