The porn industry has been doing this for a while. I remember about 4-5 years ago were services available to content producers that scanned tube sites and newsbins for copyrighted content. You had to pay for it though (SaaS, they wouldn't sell the code). It was somewhat of a racket, because the people selling the detection service were also running the tube sites that were condoning piracy. It's amazing how the porn industry is often on the front line of technology. They rarely get any notice though.
