Claimants put something at stake: false DMCA takedowns are under prejury laws which carry prison sentences.

I doubt this is really a DMCA case though. DMCA laws exist, but to invoke them requires some specific steps which Google prefers you skip.

The fact that this probably isn't DMCA may leave Google open to being sued, but you would have to see a lawyer - be prepared to spend several million dollars to win a few thousand.

Has the US ever opened a single DMCA perjury case against anyone?
