"A French court has ordered Google, Cloudflare, and Cisco to poison their DNS resolvers to prevent circumvention of blocking measures, targeting around 117 pirate sports streaming domains."

Most if not all of these domains probably use Cloudflare as their authoritative DNS servers because they are using Cloudflare CDN. Why not just ask Cloudflare to "poison" those RRs. No need to issue orders to a selection of cache operators.
