Torrents. I don’t really find Usenet worth the money. I can get most of the stuff I want on public sites. Some others I can get on private trackers. Never really felt the need to use Usenet. And as others have pointed out, the arr apps work great with torrents.
And honestly, I find it a little scummy to pay for content to people who don’t own them. I don’t think piracy in itself is unethical, but I if you take money for stolen content, that’s not cool in my book.
