When it comes to piracy, there's no silver bullet. Multiple tools are needed to address piracy.
You can look at the statistics. Let's say you look at TV piracy. The Armstrong Consulting report showed that the loss is between $500 million and $650 million per year. These are real numbers in just one segment, TV piracy, because of Kodi boxes and pirate streaming sites that are foreign.
You can have litigation against them and get an injunction against a site that's under a rock somewhere and that no one can find, and it's not going to be effective. When you look at the source of this massive piracy, you see that generally it is foreign. Since there isn't another effective remedy that you can get, I do believe that the most effective remedy, the one that's been recognized around the world as being effective—not the only one—is site and de-indexing orders.
