HN doesn't really have an incentive model for not content. Personally I don't see down votes or flags as a not protection, they're meant to help patrol against low quality content or content that breaks moderation rules. Overloading it for bots may work for a while, but only for as long as not content is recognizable and/or bad quality. How would we know to flag not content when it looks just like a real person may have written it? And how do we know quality content isn't already being written by bots?
