title: Checkbox Captcha
body: <p>I'm initiating my first start-up. I can't stand attempting to read captchas when signing up for websites, don't want my users to.  I looked for alternatives, and I found the <a href="http://uxmovement.com/forms/captchas-vs-spambots-why-the-checkbox-captcha-wins/" rel="nofollow">checkbox captcha</a>.  How is this done, using JavaScript to load a checkbox, and validate it with the same code as would normally be used to make a sign up form?</p>
  
  <p>Thanks.</p>
