Yeah, there does need to be a way to restrict bad actors. And this is already a real problem: major corporations claiming copyright over other people's original content on YouTube, and that original content getting blocked as a result. When a company does that regularly, submits too many false positives, their ability to claim ownership should be restricted somehow. At least there should be some sort of reasonable consequence. But at the very least, the original owner should retain ownership and eventually get their money again, and that's not currently happening.
