I find the opposite to be the case most of the time.
I joined in 2007, and I'm currently on the naughty step for not seeding enough, and my ratio has fallen to 0.751.
My profile stats show that I have about 35 torrents seeding. and yet 26 of these show no uploads at all. My uTorrent paints a slightly different picture, showing a total seed of 35 torrents, but with only 11 showing no activity for uploads
Clearly there was someone, somewhere who seeded the file to me, but I can't imagine that I am only one of two people who wish to view these files.
I have downloaded torrents and wait upto two months after download to see if I can obtain the file before deleting the torrent, as there are so many dead torrents on the site, mcu more than I have ever seen before.
I have the files on a standalone server on a 400 Mbps connection, with no proxy.
I'm not a wealthy man, and the donation page says 100€ to restore my ratio. However unless I change my viewing habits, or cease to use the site for downloads, this will only last a few weeks at most before my eclectic tastes once again put me on the naughty step.
