It's called the
Streisand Effect. You take down one, twelve more popup. Good example are the
http://mediadefender-defender.com/ webistes. There are about twenty of them mirrored now. All I can say is that Film artists and creators are going to have to find another way to market or distributed them, so they can "compete" with the pirates.
You can't stop piracy. But you can make it pretty difficult. Or offer perks that you can't get with the the pirate copies that would be hard to replicate. Most people who pirate probably aren't into the "bonus features." But if the content at a more reasonable price and stop lying about how th artists are starving and when in reality the money is going more to the companies. Until I start seeing actors or actresses going without food, water, their house, then I would say "Ok, then they are suffering." But if they can't afford there $350,000 car then I don't think that's a legitimate excuse to say they are "starving" or are in desperate need for money.
I always thought that if you could download whatever you want through BitTorrent, and then go to ABC and pay like $1-5 to "notarize" your content on your computer, would be a reasonable way to make sure they got something. Of course not everyone would do that, but they could always use the threat "If your computer ever is involved in any type of lawsuit or if there is a warrant (whatever) you can now have proof it's a legal copy."
That's just my idea.
