Cross-seed and autobrr. Should be enough to maintain ratios on pretty much any site excluding RED.
Just think of each site as a “game”, each one has a set of rules to work inside of, most have “cheezy” strats to min-max ratio with little effort like permaseeding small torrents for bonus points that can be exchanged for ratio.
