Used to be that shilling snake-oil (or penny stocks) to gullible citizens required you to spend significant time and effort (and money) to be present in person. And the reach of any given huckster was limited by the strength of their voice and the number of handbills they could pass out.

The wonder of the internet is that now they can do it to a virtually unlimited degree, for minimal effort/outlay. No wonder we're drowning in it.
