Using a seedbox, I consistently get >1.0 ratio on things like The Daily Show so I keep it added to Sonarr even if I'm not watching it. I use an IRC bot to grab the FL torrents when they go up so I can easily get several hundred GB of upload per FL torrent.

My ratio is so good I only have to seed for a few days (not 10 days like when you first start) so I can rake in ratio and then delete the torrent when it stops being profitable. It's mostly automated now, a bot grabs the torrent and qbittorrent's seed limits automatically delete the torrent once it gets to 5 days old. Anything added by Sonarr or Radarr is hard linked into my media directory so deleting the torrent doesn't affect anything added with the *arrs.

It's a good setup, ultra.cc charges something like $35/mo for 8TB storage, unlimited streaming via Jellyfin/Plex, 20TB of upload per month on a 50Gb connection. I highly recommend and there are cheaper packages if you're not sharing with a family or only want the seedbox to grab files so you don't need storage.
