Tor is also popular among [[Software piracy|pirates]] of software, movies and music, who most often use the [[peer-to-peer]] protocol called BitTorrent, which allows files to be quickly transferred without a central file hosting server. It is rumored that a third of Tor traffic is of torrenting. The Tor Project has urged users not to torrent over Tor because it uses too many network resources and has revealed that Tor does not provide good protection to torrenting.
