Cloudflare said using their service [can stop all spammers or attackers](https://support.cloudflare.com/hc/en-us/articles/200170066-Will-activating-Cloudflare-stop-all-spammers-or-attackers-).
How can we stop _Cloudflare spammers_ without activating Cloudflare?
Cloudflare has a massive [harassment problem](https://web.archive.org/web/20171024040313/http://www.businessinsider.com/cloudflare-ceo-suggests-people-who-report-online-abuse-use-fake-names-2017-5).
Cloudflare [shares personal information](https://archive.ph/ePdvi) of those who complain about hosted sites. They sometimes ask you to provide
your true ID. If you don't want to get harassed, assaulted, [swatted](https://boingboing.net/2015/01/19/invasion-boards-set-out-to-rui.html) or killed, you better stay away from Cloudflared websites.
