Hey man, no there is no way to trace the torrent back to you. As long as all you do is watch the video you will be safe. Also, I wanted to let you know that the guy that uploaded the torrent did not fully censor two episodes: Season 1 Episode 6 (A Golden Crown) has some minor nudity towards the end and Season 2 Episode 9 (Blackwater) has nudity from 10:40-13:21. You can probably skip the scene in Blackwater, but the other one is important. Other than that, you may want to preview the episodes to see if you are comfortable with some of the dialogue. Let me know if this works for you. If it does, there may be a way for you to use the same link to get seasons 3 and 4.
Correct. My understanding is DMCA gets IP addresses by simply entering swarms, and downloading with you. By doing so, they have a record of all the IP addresses in the swarm who connects with them. The IP address that they will see is the one from the VPN server...not yours. I suggest using one of these recommended ones. As safest to use encrypted service that keeps no logs. Ideally, overseas, too. btguard is good. https://torrentfreak.com/anonymous-vpn-service-provider-review-2015-150228/
