I'm not familiar enough to read between the lines, could you add a little context? Is the issue poor identification, or is cloudflare shielding pirates?
Obvious solution is to remove protections from them. Make them responsible if pirated material is distributed from their CDN. With the normal multipliers used in in the court cases.
Some pirate streaming services are indeed using CloudFlare CDN products, but that’s not a legitimate reason to null-route their IP addresses because that causes a ton of legitimate services to become unreachable.
