title: Contact Form submits without checking reCAPTCHA
body: <p>I'm making a webapp with a contact form, and have a google reCAPTCHA (v2) on my website to prevent robot-spam.</p>
  
  <p>I have added this code to the website:</p>
  
  <pre><code>&lt;div class="g-recaptcha" data-sitekey=""&gt;&lt;/div&gt;
  
  
  &lt;script src="https://www.google.com/recaptcha/api.js" async defer&gt;&lt;/script&gt;
  </code></pre>
  
  <p>When I try to submit my form, I'm able to submit it without the reCAPTCHA being used.</p>
  
  <p>Am I doing something wrong?</p>
