My only question is how much information about you this plan will gather. Other than that, it's not a huge deal. Whatever you may think, pirating is illegal. Receiving stolen goods is illegal. Technically they don't even need to give you six strikes, they could just track you down and haul you off to jail, let the legal system deal with you. This should also put an end to anyone who claims they didn't know they were pirating since by strike four it would just be willful ignorance on the part of the individual. Keep in mind that anyone actively circumventing these measures will likely be pilling on evidence against themselves if they're ever caught. Like I said, I do have some privacy concerns, but it so far doesn't sound like something ISPs are unable to do right now if they wanted, which is another problem entirely.
