What we seem to be discussing here is the requirement of boundaries. The limits to what are acceptable seem pretty clear in the site rules, and nobody in their right mind would expect unlawful behaviour to be permitted. But to consider advocating shutting down bad faith comments that do not breach the rules is authoritarian and in breach of freedom of speech. You sir have every right to lie to me and insult me, for example, as you would in the real world. But do so, and you lose the respect of your peers. What point is there in public witch hunts if bad faith manipulators bring themselves into disrepute?
