I know that private trackers require users to maintain a good seed ratio. How exactly does that work out mathematically? If a bunch of users have seed ratios above 1, does that mean that there are some users who will forever be below 1, and thus end up getting kicked out, thus resulting in the private tracker just… shrinking over time?
What exactly do you mean by super-seed? In torrent clients there is indeed something called super-seeding aka initial seeding but that does quite the opposite of “aggressively” seed anything. The whole point of super-seeding is to encourage other peers/leeches to share data amongst themselves and hopefully become seeds themselves. This results in your own torrent client avoiding uploading torrent data to the swarm more than necessary, it’s the opposite of building ratio if you’re minimizing uploading data.

It might be you meant to aggressively seed on an internet pipe with high upload bandwidth e.g. one of those 20 Gbps seedboxes or similar, that would make sense.
