Fix Modsecurity - Comment Spamming required shutdown of anonymous ticket creation

Preventing spam on your website without using captcha

1. Add an input field to your form, with some interesting name, for example ‘SPAM’.

      <input name="SPAM" type="text" value=""/>

2. Hide the input box using css so that users(genuine) cannot see it directly.

     <style>
      .invisible {
        display: none;
      }
      </style>
      <p class="invisible"><input name="SPAM" type="text" value=""/></p>

3. While processing the form check if the “url” contains any value. If it does, reject the post or put it for moderation.

   if (strlen(trim($_POST['url'])) > 0){
      //It is a spam, reject this post here
      }

4. works because geniune users cannot see a hidden input box on your form and therefore, they won’t fill it, while robots can.
