My experience is that just seeding what you like indefinitely is not useful. You have to be proactive and find popular torrents to seed and accrue any meaningful upload amount.

The tracker I use has a bonus point system to encourage all seeders even of unpopular releases but it's slow.

I found that the perfect solution for my use case (music) ended up being Soulseek. I don't have much money for seedboxes or buying extra storage so I feel like I'm priced out of private trackers.
