It won't work. Advertising, politics, media control, spam, religious and more groups, from a country in particular and all the world in general, are more than motivated to optimize what they do in any way, including making AIs hard to discern from real humans. We already have bots and fake accounts and whatever else in social networks trying to influence people from the dark, that will only increase.
And the alternative to that could be even worse than being exposed to that influence.
