But how? How do you separate companies with legitimate rights in a product, legitimate belief they have located someone who has violated their rights to that product and wants compensation and an agreement to stop infringing?
There was an interesting article on Ars a few months ago with an interview with a small "adult movie" company, and the piracy issues they run into gutting their revenue. How do you enable that company to send out C&D letters and even compensation requests/lawsuit threats and also stop (c) trolls?
I don't think anyone's arguing about the nessesity of regulating piracy. It's the shady companies that attempt to abuse people's ignorance of the law for profit. Google Malibu Media.
