My experience (and I’ll admit that I’ve only used a private tracker since rarbg went down) is that you can only get some seeding done within the first few hours of a new torrent going up, after that there’s just so much competition and so few people downloading, you might get a gigabyte of upload a week on a 50 GB freeleech torrent. It might just be specific to TL.
I do have a ratio nearing 10, but my upload buffer is still small enough that I don’t want to download anything non-freeleech lol
