I now use a VPN tunnel through a private (overseas) server for all my torrent needs because of this kind of crap. My ISP's IP never gets into any trackers.
There is always a way around and people will find the way, until they make all music cheap, easy to get, high quality and some way to register it so you can redownload it if you ever lose it. Not this ITUNES crap where you purchase it and get one download and if your harddrive dies and you didn't make a backup, your screwed, buy it again. I use to pirate games all the time, till Steam came around which solved the majority of my hassles with PC games.
I do find it odd an ISP would want to work with these crooks, they must be paying the ISP well for these services, otherwise what benefit is there to an ISP to kick a paying customer?
