I use SuperTorrents, it's private, you need an invite....
EDIT: Actually, you don't need an invite, but you have to sign up, and you can only sign up once per computer.
Been trying to get into Demonoid....
The pirate bay found out about Media Defender, you can find the emails about illegal methods to track people on the net.
I don't download that much anymore.... as for the movies, I hardly download anything, I'm not really interested today's movies. Same goes for music, the artists I like I support by buying it.
I grabbed the Rosetta Stone earlier this week, it took less than 5 hours and it's 2.63 Gigs. Private trackers are the best, a lot less people have access to it, = less leechers. Private trackers require you to have a certain share percentage or you get banned, which is good because everyone is giving something back and there isn't a bunch of dead torrents lying around because someone decided not to seed.
