Usenet was originally intended for sharing information but then it moved into being sort of the first social media platform then it kind of transitioned back into being mostly used for file sharing.
I can totally saturate my 1 gig internet connection with Usenet. Can download at incredible speeds. No need to ever upload. No logs of what I download. Almost instant access.
You need an indexer and you need a provider. Then you use sabnzbd to queue up what you want to download. It’s not free but depending on how much you plan to download, it’s a bargain.
For indexers I suggest drunkenslug or nzbplanet.
For a provider I suggest NewsDemon or Usenet.farm. They are both good independent providers who have helped Usenet stay alive and not succumb to corporate greed.
