Mainly just that you need to maintain a fairly high seed ratio to keep access. A lot of trackers will limit how many concurrent torrents you can have, based on your seed ratio. And depending on the tracker and the media that you want to download, you sometimes run into situations where just nobody else wants what you’re seeding, or where the torrent has so many seeds that you barely get to contribute.
Last time I was on a private tracker, I was one of only like 3 other users who were downloading episodes of Doctor Who. I could seed those for months, and never go above 1.0 because there just wasn’t interest in that.
I’m not sure if this is considered a good practice or not, but what I ended up doing was occasionally torrenting something that was really popular, even if I had no interest in it, just so that I could seed something. It definitely helped to keep my ratio up, and as far as I can tell it’s overall a net benefit to the network as a whole, so I don’t think tracker admins would have issue with it. But it just felt weird, to me.
I’m pretty sure that just doing “quick searches” is exactly how he ended up with AI answers to begin with.
