needing a paid vpn to torrent without getting spooky ISP notices is a pretty big barrier for me tbh :|
Use a p2p block list in your torrent client. Once I started using that the emails stopped.
I use: https://github.com/Naunter/BT_BlockLists/
But there are probably others
Get into a Private tracker. Or You could rent a vps in a country that doesn’t care, torrent to that server and stream or sync it locally. You would never be torrenting on your local connection.
I don’t understand how private trackers are supposed to be secure. They cannot guarantee that they keep out all bad actors and that means they’re basically the same as public trackers, just more exclusive and with a slightly lower risk because of the barrier of entry. I used MyAnonamouse in the past and back then they weren’t big fans of VPNs. But I will never use any tracker without a VPN.
