This works for me :

function role_show () {
$displayed_user = bbp_get_reply_author_id() ;
$role = bbp_get_user_role( $displayed_user);
if ( bbp_is_user_keymaster($displayed_user) ||$role == 'bbp_moderator')  $args['show_role'] = true ;
else $args['show_role'] = false ;
return $args ;
}
add_filter ('bbp_before_get_reply_author_link_parse_args', 'role_show' )

BUT

It removes the avatar from showing and the “last post by” name, on the Forums topic post lists. How can I fix this ?
