Blocklists are ineffective by design. Each and every member of the swarm can collect all the data necessary to flag you to your ISP. Obviously any professional collecting this kind of data can avoid a blocklist. There is no such thing as a better blocklist.
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.
My guess would be that companies will probably go after the 99.9% of people that torrent on public trackers, while ignoring private ones since it's not worth it to go to all that trouble just to track the last 0.1%
Never had any issues with the private tracker I'm in or got any letter from my ISP. I definitely don't pay for a vpn. I could always use my rented vps(seedbox) as a vpn if i absolutely needed or wanted to.
