Well I don't use this but I have a "friend" that uses thepiratebay.com just search for what you want and it will come up with multiple results and show u how manny people have that file, more ppl = more speed. Ps you need a torrent Tracker in order to download the files I suggest utorrent.
My "friend" uses QBittorrent to search several different sites. (though he doesn't pirate much. Mostly old NES games and such.) He also uses Ubuntu to avoid getting so many viruses. Plus, it's open source.
