Why would you report? Copyright is about money. Not your money anyway. Those who still make enough money in music or film industry have their own people to browse YouTube and report violations. All others are happy if they get more in the spotlight. Free promotion => more money. I have videos up with music that is not mine. Copyright owner (Record Company) only sent me a notification that this is their content, never asked me to remove it, never deleted my account. Band members LIKED the videos. So what?
