I would add this program if your going to use Bit Torrent in a naughty way.

It blocks off any known tracking web sites, tracking web sites use Bit Torrent to see who is downloading specific files like movies or music. They then use the IP's to report you to copy right holders and then they request your information from your ISP when they get that information they can sue for damages.
Please note that this is how it works in the US, in other countries they do not need to do as much to bust you or in other countries they could care less. You should always know your own local laws to help protect you.
