I highy recommend MTV. This is a tracker that goes by a gentlemens code when it comes to seeding. There is no strict ratio, seeding requirements, but they simply ask that you seed back for as long as you personally can without limiting upload speeds. They put trust in the community to keep content alive and in-turn everyone benefits. The fact that they rely on a gentlemens code speaks a lot about the MTV community, which is a close knit passionate community.

One of my favorite things about this tracker is the adopt the show scheme, where regular users can adopt any torrent they like (as long as it hasn't already been adopted multiple times), which means that you vow to continously seed that torrent and make it available long-term for the community. In return you gain points which can be redeemed for various things, and you gain a hearty feeling for keeping content you value alive.

This is a must-have tracker!
