Okay, I'll admit that I'm not a lawyer and that I don't know the actual legality of these things. However, I would like to respond to one statement:

Everytime he hits a porn site, this information is available to that porn site.

Correct, the information is available to that site. However, if that porn site were to turn around and say "On this date/time, the following IP address accessed my site and downloaded illegal photos of minors", and they were to give that information to a private individual without a warrant, that would be (as I understand it) wrong. Even though the act of performing that download is illegal, the individual has a right to his privacy until a court deems the information necesssary in a criminal case.

I could be incorrect about the legality of this situation. Does anyone have any definitive information on this? Not just an opinion?
