Reality tv is hit or miss depending on popularity and how old it is. Retention plays a part is this too, but most Usenet providers worth subbing to have crazy long retention times.

I personally use Sonarr for tv and it’s stupid easy to use (once everything is set up!), you just search for your show and it knows when it airs and auto-grabs new episodes. You can also tell it to look for past seasons.

The whole “getting Usenet setup and running” is a little more complicated than I’d like to get into with this post, but you’ll need the following: a Usenet provider, an indexer (both of these will cost money but it’s not a lot and annual payments, or lifetime, is usually the way to go), a newsreader (I use SABnzbd), and a web app to track shows and initiate searches (I use Sonarr, as previously mentioned).

I’m sure someone else here can post a link to a good guide to getting started with Usenet if that’s the direction you want to go.

TLDR: it depends on the show
