Cloudflare, the criminal's choice
Cloudflare is also pretty well known for shielding criminals, booters, and even ISIS.
I've tried to work with them over a copyright infringement site they were shielding and got nowhere.
"CloudFlare, a content delivery network that provides free "Universal SSL" to its customers, is a hotspot for deceptive certificates, accounting for 40% of SSL certificates used by phishing attacks with deceptive domain names during August 2015."
The booter services are proliferating thanks mainly to free services offered by CloudFlare, a content distribution network that offers gratis DDoS protection for virtually all of the booter services currently online. That includes the Lizardstresser, the attack service launched by the same Lizard Squad (a.k.a. Loser Squad) criminals whose assaults knocked the Microsoft Xbox and Sony Playstation networks offline on Christmas Day 2014.
The sad truth is that most booter services probably would not be able to remain in business without CloudFlare's free service....
