A highly controversial court order that required Cisco, Cloudflare, and Google to poison DNS earlier this year was just the beginning. To further combat sports piracy, broadcaster Canal+ sought several follow-up orders. Cisco had discontinued its OpenDNS service in France due to the legal restrictions, so only Google and Cloudflare put up a defense, but without the desired result.
Yeah ud have to blackhole the ip. Which would mean u would need a national firewall filtering every single citizens network traffic. It might also violate net neutrality. Plus ud also have to bully every single satelite internet company into complying (good luck with elon lol).
Its possible but would be a right pain in the ass and huge violation of internet freedoms and possibly free speach itself.
