They become fully liable. So, sue them.

I'm sure you registered your copyright within three months of first publication because you recognized its value, right? And so you can recover attorney's fees, right?

And yes, all the steps against hosting companies and internet connections that do caching are excellent ideas. Don't forget the image hosts for vidcaps. Don't forget the privacy escrow registrars. Hell, if you are on a roll, send a DMCA to the domain registrar.
