The cynical part of me wonders if this is no more than a PR exercise from Cloudflare and whether 8chan were actually a paying Cloudflare customer or mealy using the free services to reduce server load and to protect themselves against DDOS attacks?
Where as Cloudflare are obviously entitled to decide which sites they want as their customers by actively removing some sites surely they are opening themselves up to be liable as a publisher if they then at a later date decide not to remove another website that is also allowing hate speech?
