    Example migrated from Codex:

    The example below remove the URL from the comment author text (comment_author_url) and changes the first character of each word of the comment content to upper case if it’s in all upper case.

    add_filter( 'preprocess_comment' , 'preprocess_comment_remove_url' );

<?php
function preprocess_comment_remove_url( $commentdata ) {
   // Always remove the URL from the comment author's comment
   unset( $commentdata['comment_author_url'] );

   // If the user is speaking in all caps, lowercase the comment
   if( $commentdata['comment_content'] == strtoupper( $commentdata['comment_content'] ) ) {
      $commentdata['comment_content'] = ucwords( strtolower( $commentdata['comment_content'] ) );
   }

   return $commentdata;
}
?>
