Comment (by devspace):

 Create a Custom Filter: You could create a custom function that checks the
 raw comment data before passing it through the normal WordPress filters.
 Here's an example of how you might implement this:
 {{{#!php
 <?php
 add_filter('pre_comment_content', 'custom_check_disallowed_keys', 9, 1);

 function custom_check_disallowed_keys($comment_content) {
     $disallowed_keys = array('href=http'); // Add other disallowed keys
 here

     foreach ($disallowed_keys as $key) {
         if (strpos($comment_content, $key) !== false) {
             wp_die('Your comment contains disallowed content.');
         }
     }
     return $comment_content;
 }

 }}}
