Which is why the ISPs will challenge the law in court when and if the MAFIAA attempts to bring suit for failure to "cut off" a customer(s).
That sounds reasonable at first glance, until you realize that for many people their ISP is also a content provider (e.g. Comcast), who has just as much or more financial interest in selling you TV/movies/music than they do in selling you Internet service.
If this "three strikes" approach becomes common, how long do you think it'll be before the big ISPs begin to offer Internet service packages (called something else, of course) that provide access only to content and services they or their affiliates control? It's a very attractive route to reigning in all this wild proliferation of options and getting thing$ back to where they belong.
It's nice to hear about a dire environmental threat that for a change we can't make any worse by ignoring Global Warming.
