I have a paid Usenet account with good retention and I download through sabnzbd. I’ve only ever used nzbindex.com as an indexer.

For a long time it was easy to find TV/movies but in recent years it’s become almost impossible. Has Usenet become a bad option because of takedowns or am I missing a modern way of using it?

I see there are lots of binaries posted with cryptic or random string names. Are these supposed to be regular TV/movies etc. with obfuscated names so they can’t be found and taken down?

Do better/private indexers give access to these files or otherwise solve not being to find anything? Is it still supposed to be possible to find reliable new release shows and movies?

Are Sonarr/Radarr are what I need, do they solve the problem of not being able to find files, or do they just provide more convenience for the same files I can already find?
