I've had experience with those YouTube automatic copyright filters. I used to teach an online and televised class on Labor Law, which was posted to YouTube after each lecture. I often used clips of Sponge Bob to illustrate my points. (Yes, there is a Sponge Bob episode on sexual harassment, union organizing, and plenty of other labor law issues arising from the ultimate capitalist - Mr. Krabs). Every time, an autobot protest from Viacom would come in. As you indicate, there is some kind of code embedded in those tracks which triggers the protest. The University would respond, indicating "Fair Use" for educational purposes. As far as I know, it would eventually get back on You Tube. You can check if it is still there at:
