If no one is allowed to post anything on line unless it constructively contributes to a debate, the police are going to have to abandon all other duties. And presumably sit in pubs and other public places to police everyone's conversations at all times to be appropriate, polite and constructive only?
The punitive desire behind the reporting is being made plainly apparent, which is a good thing. It is not enough to remove what has been said, the sayer must be punished.
