After rarbg went down, I got into a private torrent site. They expect everyone to maintain a certain ratio, which is reasonable, but there is actually no way to build ratio. The seed-to-download ratio is ridiculously high for all of the popular torrents, and new users aren’t allowed to post their own torrents. (As a sidebar, normies seem to run the Internet now, so all of the most recent torrent offerings are bad network TV shows, Marvel movies, or equally unwatchable fare).
When I was on Demonoid during its heyday ~20ish years ago, the standard way to build ratio was to offer something for download that nobody has, allowing your ratio to grow by uploading to the first few initial seeders.
This is not possible anymore, at least on this private site. Is this normal, or is this private torrent site just stupid?
For starters, many have mentioned freeleech torrents to build ratio, you can also add stuff you already have by downloading the same release from their site and setting the directory to where you already have the files (this only works for releases that are identical though), if your internet is fast enough, you can snag just released torrents (the more popular you expect it to be the better) and reseed to other people as they get it. This only works for torrents that are within a few minutes old though.
Past that look into getting a seedbox or set up an old/cheap computer to run constantly and download your torrents to that, and just transfer them to your main pc as you need them.
