Hey, yes there is. I was 100% torrents up until recently, also using multiple torrent sites including private trackers. The thing I struggled with was getting all the episodes of TV shows. Like if I added a niche or old TV show to Sonarr, it would be a constant struggle to find missing episodes or seasons (for some reason Southpark was a misery). This was pretty much completely eliminated with usenets. So now I have usenets as a primary and torrenting as a fallback if something cant be found. This config gives me almost full coverage. The downside is that usenets typically aren’t free whilst torrenting is (although they are very cheap)

Yo if you ever find a good source PLEASE tell me, this is a constant struggle for me too, I will return the favour
