If you ever read any of those notices you'd see that it only has an IP address of the offender (which is not rocket science to work out) and the alleged copyrighted work. So what you are saying is that anyone that uses P2P (which will reveal your IP and the files you are downloading) is invading privacy? Furthermore what I don't understand is how one can blindly turn away from an AUP that everyone agreed to? Just by "using" your connection you are bound to these terms... If the AUP states "Thou shall not copyright", and they catch you, why are you upset?

Also, reading the mentioned BayTSP's faq (

In a nutshell all this article shows is the ignorance of people that don't want to play by the rules and find it sensational to move the focus away from people whom really ARE breaking the law to someone that is preventing it from being broken.
