I'm bored with this. It has always been, since time began, the copyright holder's job to police their own copyright (in the US anyway). The fact that the internet makes that harder to do doesn't change that. "Copyright Police" of any kind (be it government, private, or robo-algorithms) will be far more dangerous/damaging/intrusive than any harm that piracy does. "The bark is worse than the bite." "The cure is worse than the disease." You get the idea.

(Rhetorical yous from here on out)

You hold copyrights? Do your DD. You issue the take-down requests. You take them to court if they refuse. Protecting your copyright is your job, and not society's.
