Are all invite-only torrent sites like this?

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?
