Speaking of racketeering, it's an enlightening experience to search for "stresser" or "booter" providers (euphemisms for DDoS-as-a-Service) and look up their NS records to see who helping them ward off competitors DDoS attacks and keep their origin servers hidden. 9 times out of 10 it's Cloudflare, with the few exceptions being DDoS-Guard, who more or less specialize in facilitating crime.
