Often torrents will also state "This studio has been aggressive towards file sharers and torrenters. Do not download this unless you are confident that you have taken steps to maintain your anonymity. GT members, especially those in the US and Germany, should not download this content without use of a reputable proxy or vpn. More information here." From what I understand (and believe me it is very little) if you pay for these proxies any identification is disguised and downloading cannot be tracked to you. Of course you pay for any proxy and some are better than others. I am not sure how well they work but there are serious discussions in various forums on torrent sites.
