The development of network technologies has only aggravated the situation. In the past, pirates used to steal only ready content (movies, musical compositions and software), but now they are stealing Internet broadcasts of various events and channels too. It is difficult to estimate the amount of money lost by a right holder who organized, suppose, a pay-per-view broadcast of the World Cup Final. Immediate reaction in an online mode, literally is required to detect and put a stop to this infringement.
So you will be helping content creators to find and ban illegal sites? I wish we will know someday how many sites and illegal content are downloading every minute in global network.
You must fight with users and hosting providers (the last one is more preferable). Companies must create rigid criteria for new users and sites, only this way you will be able to fight with copyright breakers.
