I was just cleaning up some code on my site and noticed a small security hole in my comments sections. Every time I posted a comment, WordPress automatically added a class that pretty much told everyone my admin login name. The offending class is the “comment-author-admin” class. If you had changed your admin name to bavotasan, then it would read “comment-author-bavotasan”. Not too secure if you ask me.

I created a code snippet that can quickly remove the offending class from every comment. Just add this to your functions.php file:

function remove_comment_author_class( $classes ) {
	foreach( $classes as $key => $class ) {
		if(strstr($class, "comment-author-")) {
			unset( $classes[$key] );
	return $classes;
add_filter( 'comment_class' , 'remove_comment_author_class' );
