Please, tell your friends to stop relying on CloudFlare.
Why?
1) It's an intercepting proxy. All traffic is logged and shared (sold) to third parties - mainly the feds,
2) CF can inject a malicious payload,
3) CF adds unnecessary captcha to, inc but not limited to, privacy-aware visitors (VPN, TOR), or block them completely,
4) the internet is basically unusable with CF blocking browser addons,
5) If CF goes down, your website will go down, too. And yes, it does happen.
