Trying to stop piracy, eh?
China has something like this. You know, the "blocking websites" part? Yeah. Yet we still do a truckload of software/music/movie pirating. In fact you could say it's almost a lifestyle. Just ask the next guy, "Hey, how much is that game?" and he'd reply, "Oh, this one? I got it off some torrent," or "Oh, about 15. I got it from that guy from that so-and-so place."
Not gonna' work very well, this bill. It's gonna' stifle a lot of things, for sure; But piracy? Piracy is just gonna' expand and advance even more. The only way to combat it is to provide inimitable and satisfactory services/extra contents for your product. Like what Valve is doing, for example.
