Nope, he didn't even upload anything. He must just have a mega-super-dooper connection. Either that or he spent loads of time grabbing the really popular stuff just for the sake of it when it was first put up.
The only reason I got my own ratio above 1 was that over Christmas they had a 'leechfest' where you could dl whatever you wanted, and it wouldn't affect your ratio adversely, but whatever was uploaded would still be counted. So I just kept grabbing all the things with loads of leechers. Before that I struggled to get it over about 0.5.
If it hadn't been for the bastarding earthquake halfway through, I would have a ratio of about 2 by now.
