the hot feed is the same as reddits rising feed. its not a hot feed, its just random posts that have gotten an above average number of upvotes in the last hour. this site is next to impossible to use between the lack of a hot page and all of the niche communities not being populated thus making the front page and your subfeed the same 5 communities, and they’re all memes.
Sharing torrents in a private group is a zero sum game. Ideally you have everyone with a 1:1 ratio but if some users go far above that they are taking ratio from other users who might be fully willing to provide upload, but simply didn’t get there in time. You can set torrents to close after they reach a specific ratio, but that also means bringing down the availability of that torrent.
Also, it’s much harder to get to a 1:1 ratio if you only download less popular content because no one will download it from you for a long while.
