Suprnova is ok, however it is monitored by certain legal agencies.
The best thing to do is try and find a few private trackers and become a member. There are some out there, however the people that use them are tight lipped because when one type of person becomes a member and tells one other person, there are soon thousands of people leeching and not seeding 1:1 ratios, therefore ruining the torrent. Oh and the trackers and tracker servers get hit with thousands of people wanting to download.
If you can find some private ones, you are lucky.
