quote: SOPA changes it so that the infringer's service provider is also liable. The service provider has no idea if any infringement actually occurred, and (assuming they have lots of customers) little interest in preserving the infringer's business or financial integrity. They just want to cover their own butts to make sure they aren't sued for something someone else did without their knowledge.
quote: So the copyright holder sends a claim of infringement to the service provider. The service provider acts in self-interest and immediately shuts down the alleged infringer's website. The alleged infringer is then put into a position where they have to prove that they didn't infringe in order to restore service. No court, no injunction, no hearing, no due process.
