> At least the DMCA in the U.S. has guardrails: not just anyone can send a takedown demand for everything. The requester has identify the works and declare under penalty of perjury that they are operating on the behalf of the owner.

DMCA came into effect 28 years ago. All those decades, all those billions of takedowns, and you don't even need the fingers of one hand to count those who've been hit with perjury for a false takedown request, because the number is ... zero.
