functions.bb-template.php line 1866 shows the arguments that this functions can accept, including a before and after character. But it also states $args = null. You could add the | on line 1868 but this is editing the core

Alternatively use an if ( bb_current_user_can( 'view_by_ip' ) ) { echo " | "; }.
