Without a high enough upload bandwidth (only have 5Mbps myself), even with freeleech not counting against one’s download for the ratio it’s unlikely that peers will stay connected to download seeded releases when other people with far higher upload bandwidth or seedboxes can maximize their download bandwidth. Not a problem for everyone of course, but the 100-torrent method works whether someone has an upload bandwidth of 1 Mbps or 1000Mbps.
