Actually not rated. But that doesn't mean anything goes. Depending on what was said or message sent. Harassment of a minor (if proven) can bring enforcement by local gov't. Many western gov't are bringing in very tough anti bullying laws. To target people who target legal minors. Whether or not the minor should be in a certain place or not. The laws are changing for online interactions. So i 'd be very wary of sending an obscene message to anyone.
