You are still presuming that some third party has the right and/or authority to dictate what my ISP may or may not allow. We have arrived at the point we are at today, because the MAFIAA's of the world have bullied the world into believing that they have some kind of authority.
In an ideal world, where your rights are actually respected, the MAFIAA's would be required to present each and every case of "piracy" to a court before the court would issue a subpoena to the ISP to reveal any customer's identity. Then, and only then, could the MAFIAA initiate a suit against you - just you, not a long list of John Does.
What would happen here is, the MAFIAA would have to spend a considerable sum of money on each and every prosecution, so they would ONLY go after big time operators who were profiting from the piracy, and actually cutting into their profits.
This whole business of using some torrent logs to demand the identities of thousands of people to mail extortion demands is preposterous. Everything in the system is just wrong today.
And any rational person can readily understand that the MAFIAA's are outright lying anyway. Each and every year, the MPAA posts record breaking profits. If piracy were damaging the MPAA, they couldn't break each new record the following year again. They would be posting LOSSES!
