I'll admit, when I first started torrent I was not really familiar with how it worked and how important seeding was. I would just use magnet links without configuration to save the torrent and seed after completion. Well.. I have finally, got myself back to 1.00 after a couple months and working to try to always seed double what I get for each torrent.
Often times I was one of the few random seeders available for some of these torrents. Friendly reminder to give back because you never know when you're one of the rare cases that can complete someones long lost file download!
I just use a Debrid service for my torrents now. Consistent 1Gbps download speeds and no ratios to worry about. It's way better (and cheaper) than a private tracker or a seedbox.
Had any trouble finding obscure stuff?
No more than I would if I used a Torrent client instead of Debrid. You're still downloading the same torrents as everyone else. (I don't really understand the question.)
With torrents you're limited to the networks and sources that you have connected. The torrent client search for example is very limited, that's where the trackers come in.
The question is how debris compares to stuff that is not found on public trackers.
An easy test are niche audiobooks or foreign movies - those are quite rare/specialized.
IDK I only use public trackers.
