What do the CloudFlare CAPTCHA and Challenge pages look like for users?
<p>In the CloudFlare <a href="https://www.cloudflare.com/waf/" rel="noreferrer">Web Application Firewall</a> you are able to block, whitelist, CAPTCHA, or JavaScript Challenge traffic based on IP address, country name, or ASN. The only note provided on the CAPTCHA section is:</p>

<blockquote>
  <p>If you are unsure whether suspicious web visitor behavior is illegitimate traffic, you can set up a challenge page. This page asks visitors to submit a CAPTCHA successfully to continue their action. If the web visitor fails the challenge, they will be blocked from your website.</p>
