I used Turbobit torrents system and it works pretty good (and fast even from The Piratebay).
One major disadvantage: it doesn't seed so expect your ratio to go down on private trackers.
1) Turbobit, doesn't require premium for torrent upload
2) Bulldozerproject - > crocko
3) cramit.in
Aren't there going to be issues with private trackers, apart from ratio, considering they will see you downloading from a different ip?
You are also sharing your passkey with whomever runs these services: could this be an issue?
