There is another way to fight pirates. Not sure if it would work, but it scares the life out of pirates.
Sue the guys doing the uploading. Find them and summons them. Offer to settle out of court or go to court. Then let the uploaders and downloaders know what you're doing. Tell them you will share part of the winnings for the information on who is pirating content. Pirate Bay might need some money soon.
I posted on a file sharers forum that this was the route
www.pak-inc.com are going and it scares them. They start by saying we can't find them, then asking if it's good for our image and end up bleating we are being unfair.
The thing that makes pirating a problem is the lack of penalties pirates face. Let them know they might get caught and sued and the problem will decrease. Not easy, but is it possible?
