Disable HTML in WordPress Comments

I absolutely hate SPAM in my comments.  I fantasize sometimes about sneaking up on would-be spammers with an iron skillet just before they can hit send.  Okay … assault is a bit excessive, so shy of committing a felony, how can we slow these spammers down?  One way is to take away the HTML privilege from commenters.  Add the following code to your functions.php:

1

// This will occur when the comment is posted
function plc_comment_post( $incoming_comment ) {

// convert everything in a comment to display literally
$incoming_comment['comment_content'] = htmlspecialchars($incoming_comment['comment_content']);

// the one exception is single quotes, which cannot be #039; because WordPress marks it as spam
$incoming_comment['comment_content'] = str_replace( "'", ''', $incoming_comment['comment_content'] );

return( $incoming_comment );
}

// This will occur before a comment is displayed
function plc_comment_display( $comment_to_display ) {

// Put the single quotes back in
$comment_to_display = str_replace( '
'', "'", $comment_to_display );

return $comment_to_display;

WordPress Rocks! If you can dream it, I can create it!
