By default, WordPress allows blog commentators to use HTML in their comments. However, you can easily notice that this feature is mostly used and abused by spammers to create numerous links to their fishy websites.

To get rid of HTML in comments on your WordPress blog, you need to paste the following code in the functions.php file of your WordPress theme:

function plc_comment_post( $incoming_comment ) {
  $incoming_comment['comment_content'] = htmlspecialchars($incoming_comment['comment_content']);
  $incoming_comment['comment_content'] = str_replace( "'", ''', $incoming_comment['comment_content'] );
  return( $incoming_comment );

function plc_comment_display( $comment_to_display ) {
  $comment_to_display = str_replace( ''', "'", $comment_to_display );
  return $comment_to_display;

add_filter( 'preprocess_comment', 'plc_comment_post', '', 1);
add_filter( 'comment_text', 'plc_comment_display', '', 1);
add_filter( 'comment_text_rss', 'plc_comment_display', '', 1);
add_filter( 'comment_excerpt', 'plc_comment_display', '', 1);

    I am definitely guilty of messing up my computer on more than one occasion by clicking on those links. It would definitely be a service to readers to get rid of them on our sites as well!
