Your question is so generic that it is difficult to reply. I’ll tell you about my use case then so that you can try to figure out yours.

My goal is to be a respectful citizen. I divide my torrents in three categories:

• rare stuff: for example project 4k77 or the John Wick regrades or Rashomon
• italian stuff: it can be either popular stuff and also rare stuff; italian content is not seeded much so I need to do my part
• common/popular stuff: for example the barbie movie or every marvel stuff

I bought tons of space (recently converted to three drives, 20tb each) and use a virtual machine locked behind a vpn. Even if I forget to paid, the virtual machine is bind to the tunnel so that traffic doesn’t go out except for LAN, so no leaks.

The VM has two torrent client:

• qbittorrent: seed the torrents in the common / popular categories, speed capped to 1/3 of my bandwidth
• transmission (previously using rtorrent) for the other two categories

I tend to leave everything in transmission seeded forever, the stuff in qbittorrent seeded until 2.5 ratio or 4.0 depending on my mood.

At the moment I have 90.2 ration on transmission and many many many TB of uploaded stuff. That should be enough to feel like you are giving back
