You basically have a remote server, usually a cloud or bare metal, where you do all your torrenting. It’s fairly easy, as there are plenty of clients with web UI like Transmission that can be setup super easily via Docker. Make sure to protect it somehow though. Or use a torrent CLI tool and do everything via SSH.
Fun fact, apparently nature can only do fractals 4 levels deep. This works for romanesco, fern, and tons of others. I am yet to find an outlier.
