Has this been discussed anywhere? (How to fight back).

In the last week or so, I have heard indirectly about the exact methods the Russians used to try to influence the election. I don't have links, but I understood it to be very finely targeted messages to vulnerable people. Vulnerable people were identified using big data and the kind of techniques employed by Analytica in Cambridge.

If this is true, then is anyone writing algorithms to identify THOSE SAME PEOPLE to flood them with counter arguments? Obviously they're not primed to believe the counter arguments, but it can't be OK just to cede the media to fake news.

Is anyone talking about this?
