See the comment from the employee saying that the company will simply wait a little while then have the system re-upload the content. Then wait for another DMCA notice. Then go through the whole process again.
I'm assuming this business model is the exact same for tubes, file lockers, torrent sites, image hosts and every other site that profits from user uploaded copyrighted content?
Delete the offending shit, wait a while, then have your Indian uploader whack it back up later. Different user account, IP etc.
The companies are simply unstoppable then, aren't they? How can you hope to punish a company that follows the DMCA? "We didn't know a user re-uploaded that content. Look, we've removed it again.

"
What else can be done? Not in the future or how it should be. I mean: what real life legal practices can be done to stop a company doing this?
