Cloudflare also has an added appeal to sites such as The Daily Stormer. It turns over to the hate sites the personal information of people who criticize their content. For instance, when a reader figures out that Cloudflare is the internet company serving sites like The Daily Stormer, they sometimes write to the company to protest. Cloudflare, per its policy, then relays the name and email address of the person complaining to the hate site, often to the surprise and regret of those complaining.

And, by The Daily Stormer’s account, advice and assurances. In a post, the site’s architect, Andrew Auernheimer, said he had personal relationships with people at Cloudflare, and they had assured him the company would work to protect the site in a variety of ways — including by not turning over data to European courts. Cloudflare has data centers in European countries such as Germany, which have strict hate speech and privacy laws.
