title: Getting spam Emails after integrated Google reCAPTCHA v2
body: <p>I have implemented reCaptcha in TYPO3 website and after integrated Google reCaptcha V2 api even I am getting spam emails. In reCaptcha admin panel I did not see any erros and warnings messages. I also implemented server side validation and Verifying the user's response. </p>
  
  <p>But I did not understand why I am getting spam emails after integrated reCAPTCHA?</p>
  
  <p>Server side Validation</p>
  
  <pre><code> if(isset($_POST['captcha']) &amp;&amp; !empty( $_POST['captcha']) &amp;&amp; ($_SERVER['REQUEST_METHOD'] == 'POST')){
             $captcha=$_POST['captcha'];
           }
           if (empty($_POST['captcha'])) {
             exit('Please set recaptcha variable');
           }
           $secret="************************************";
           $response = $captcha;
  
           $verify = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret=' . urlencode($secret) .  '&amp;response=' . urlencode($response));
           $captcha_success=json_decode($verify);
           if ($captcha_success-&gt;success==false) {
             echo '&lt;h2&gt;You are spammer ! This user was not verified by recaptcha.&lt;/h2&gt;';
           }
           else if ($captcha_success-&gt;success==true) {
             echo '&lt;h2&gt;Thanks for posting &lt;/h2&gt;';
           }
