Why do torrent sites rank so high on Google?

I don't know, maybe alexa ranking? they have heavy traffic...
I think, like affiliate_onlinebiz said, it is because they are constantly updated with fresh content. They most likely feel the same effect that forums do as far as SE indexing.
Yeah, I think they have automatic generated keywords. So they rank in all these keywords for stuff that gets like 15 searches a month.
a lot of people backlink to them because they love the site since it provides free stuff
