I use BlackCats.
Can't say that I like it though. Full of dickheads, there are a lot of people that know what they're talking about there. Though.
Their rules suck.
Individual torrent ratio over overall ratio.
and;
ZOMGZ LAWLZ YOO LEECHED ONE TORRENT NOW YOU'RE BANNED FROM DOWNLOADING UNTIL YOU RAISE YOUR RATIO TO 96.238593876983
Lucky enough I've screwed them over many of times. I've never seeded a gig of my upload, and I've leeched every damn Xbox game I could.
I think I'm onto like my 5th account now, there.
