So many posts about torrents. It seems if you are concerned about privacy you really should learn more about how the bit torrent protocol works. Your ISP looking at your traffic should be the least of your privacy concerns using in-the-clear-torrents. Since ISPs typically are not in the copyrighted material business they have little incentive in turning in their customers. What companies spend time and money on activities that don't generate income or reduce expenses for them.
Look at your BT Client! see all those IPs? Those are people seeding/leaching that torrent, you don't need to be an ISP to see that data.
Clients like OneSwarm are capable of hiding your IP, and provide more anonymity, but sadly most torrents are in the clear and it won't make any difference for those.
Bottom line if you are doing illegal shit on the internet, use caution. Use proxies, encryption, public hotspots, etc, when possible. Learn what logging, tracking policies are in place by the ISP and their policies in giving up that data to 3rd parties.
Don't expect your privacy rights to be around forever, The U.S. Plutocracy, will disassemble that mechanism in time, if it will lead to larger profits. Act now and learn to protect yourself.
