 wp_update_comment needs a filter
 Prospective Update: Here's what the filters might look like:
 {{{#!php
 <?php
 /**
  *  To be able to add additional checks
  *  such as (empty comment_content, same content...etc)
  */
 $commentdata = apply_filters( 'wp_update_comment', $commentdata );
 if ( ! $commentdata || is_wp_error( $commentdata ) ) {
         $message = apply_filters(
                 'wp_update_comment_error',
                 __('We apologize, but an error has occurred while
 processing your request'));
         do_action( 'wp_update_comment_error',$commentdata);
         if ( defined('DOING_AJAX') ){
                 die($message );
         }
         wp_die( $message, 429 );
 }

 }}}
