It's funny that private trackers are now more about ensuring uploads are high quality and properly labeled, and that people actually seed, than they are about dodging copyright enforcement.
Reflective of the times. Most people on the internet don't know how to install a torrent client, or even download a file. (Because most people on the internet are on a phone. I don't even know if it's possible to torrent on a phone.) And the stuff people download is mostly "free" anyway via Netflix, Spotify and other content streaming services. A download no longer represents a lost $50 Blu-ray or $20 CD sale to the bean counters, it represents a lost $0.01 streaming royalty. It seems like the only time copyright enforcement bares its teeth these days is for live sports matches.
