Comment (by ocean90):

 6 years ago we had already removed the referrer for comments, same reason,
 see #1673.

 Also many plugins already includes a referrer check.

 Code snippet:

 {{{
 function my_verify_comment_referer() {
         if ( ! wp_get_referer() )
                 wp_die( 'You need to enable referrers in your browser.' );
 }
 add_action( 'pre_comment_on_post', 'my_verify_comment_referer' );
 }}}
