Actually, I don't agree - to my mind, the DMCA (as much as I disagree with most of it) already provides a mechanism for the situation to be handled: if we find our content on your site, we send you a notice; to be eligible for "safe harbor" status, the site must take the content down.

We've already seen that this law is often misused by large-scale content creators (see: Warner and Hotfile, various music labels issuing takedowns on files uploaded by their own artists). I don't know why I should expect that giving additional power to those most likely to misuse it is a good idea.
