I know some people who work in SEO and marketing and the stuff CA was doing was a more sophisticated version of what every free Facebook game or 'survey' vendor is doing. This is literally the business model of the free/popular Internet. Of course it's going to be used for political campaigns-- why not? It's used for every other kind of marketing.
I'm not saying it's good. I think it's terrible. It's a plague. I'm just shocked that people are shocked by what's been happening in the open now for years.
