A few months ago I grabbed this torrent from rarbg, and it took weeks to download. Often going days with no seeders.
I finally got it, and decided I’d seed beyond my usual 2x to help others get this. Then rarbg went under, and now I think I’ll just keep this one going.
Yay.
Sometimes certain debried like Alldebried might be able to get you the torrent without any seeding p2p.
But they might be a paid service so that’s up to you.
Only if it’s still cached on their servers. If the torrent has zero seeders and it’s not cached even the debrid sites can’t complete the download on their side.
