Ratio on private trackers isn’t really a big deal as long as you’re the kind of person that can keep a couple hundred GB worth of things seeding close to 24/7. Aside from actual ratio(the thing your torrent client reports), they tend to have a system that rewards having things seeding, whether anyone actually connects to you or not, that you can use to boost “ratio”. There’s also usually some options for acquiring some content without it counting against you, like freeleech(download data isn’t counted in your ratio) for low seeded or new torrents, or discounted/refunded credit for extended seed times, or seeding large amounts of data. Aside from the first few months in a new tracker, ratio isn’t a big issue.
