We don't feel that the notice and notice has any teeth to it because, as copyright holders, we would go to the ISPs, and then they would inform whoever's violating. That's not strong enough.
Again, as Graham said and Loreena said, we don't want to sue our own customers or go after the people that buy our music. For the folks who are commercially stealing our copyrights, we need stronger weapons than a notice and notice. That's not going to do anything. It's not going to change anything for us.
