One would assume that they simply block any infringing torrents once those have been identified by a copyright holder, or something like that, though I honestly don't know what they do. But I would assume that they do something, because they're likely to be talking to a lot of lawyers soon if people start using it for piracy.

That said, I'm not sure how letting people download it from their servers is any better than sending it on a DVD, and an envelope full of enough DVDs has a much higher bandwidth (and a much higher latency) than most internet connections in the USA.

If anything, the fact that a human would probably have to handle the DVD to put it into the mail would be a better copyright filter than most programs. "Oh, hey, this is that new movie. Nice try. tosses DVD into trash"
