I love how this guy is treating this like it's an inquisition. WE'RE THIEVES! FELONS, EVEN!
Oh, and that whole "cut off the internet" plan will fail. Why? Because so many people download illegally. If you try to get rid of EVERYONE who has downloaded a song illegally...well, you might as well just say goodbye to the majority of your customers. Even some people who buy albums on a regular basis have obtained music in an illegal fashion.
If you really want to hit the downloader where it hurts, seek out those who have made the songs available for illegal downloading.
