Mod for deleting unapropriate tag multi word tags

Hello, very nice work, simple and efficient, but it lacked the ability to delete some of the tags… so i added two lines in the dk_save_post() function, you can add it in a later release ??

function dk_save_post(){
  $tags = get_tags( array('hide_empty' => false) );
  $post_id = get_the_ID();
  $post_content = get_post($post_id)->post_content;
  $post_title = get_post($post_id)->post_title;
  $post_status = get_post_status();
  if($post_status == 'draft'){
    $d = strtolower($post_title.' '.$post_content);
    $options = get_option('aat_options');
    $whole = $options['whole'];
    if ($whole=='checked') {
      $x = array(',','.','?','"','\'');
      $dummy = str_ireplace($x,'',$d);
      $m = explode(' ',$dummy);
      if ($tags) {
        foreach ( $tags as $tag ) {
          $composed = strpos($tag->name, ' ');
          if($composed === false){ // simple  tag
            foreach($m as $n) {
              if (strtolower($tag->name)==$n) wp_set_post_tags( $post_id, $tag->name, true );
            }
          }else{ // multi words tag
            if ( strpos($d, strtolower($tag->name))) wp_set_post_tags( $post_id, $tag->name, true );
          }
        }
      }
    } else {
      if ($tags) {
        foreach ( $tags as $tag ) {
          if ( strpos($d, strtolower($tag->name))) wp_set_post_tags( $post_id, $tag->name, true );
        }
      }
    }
  }
}
