This also demonstrates why it is bad for a law to mandate private entities to do moderation, in this case taking down copyright infringement materials when reported. Google, like basically all big platforms, doesn't care if a claim is fraudulent because the parties impacted cannot hold it accountable — google will just tell you they are themselves victims of the fraudulent claim. And to be fair, they are. But it has to enforce the claims or else lose its safe harbor exemption. This practically allows bad actors to use platforms as their shields, and in the end no one but the victim suffers any consequences for their abuse of the copyright laws.
I think a more sane approach would to require every copyright takedown to require a court order. Granted, the legal system is not perfect, but judges are not incentivized to always side with the supposed copyright holder like online platforms do. They will not be letting someone claiming to be living on a deserted island to file a claim and even when fraud does occur, they will at least know where the claim is actually coming from and be able to punish the fraudster accordingly.
