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.
