Torrenting over Tor
The Tor project strongly recommend not to torrent over Tor! It is recommended to use a torrent-friendly VPN instead.
Tor improves internet users privacy and security and is the easiest way to browse the web anonymously. It can be used to access blocked torrent sites from everywhere in the world.
Torrenting over Tor is not a good idea, here is why: Tor doesn’t have the capacity to support high bandwidth apps like BitTorrent clients. If too many users would torrent, the network will saturate to a standstill. Accessing blocked torrent sites and downloading the .torrent file over Tor is fine.
