The Guardian has an article about a whistleblower from Cambridge Analytica, who claims to have devised a strategy to "weaponize" Facebook profiles, in order to use those profile for targeted advertising to sway the US elections in 2016.
(The Guardian headline titles are often crap). I read a few older articles, presumably by the same author: she had a series of articles in March--May 2017 about Cambridge Analytica being used as a weapon to convince British voters to vote for Brexit in the referendum. It seems that her investigative journalism encouraged this wistleblower to "come out" and be interviewed by her.
Here's one: https://www.theguardian.com/technology/2017/may/07/the-great-british-brexit-robbery-hijacked-democracy
Democracy is the worst form of government, except for all the others (Churchill), but when does advertising cross the line into psychological warfare against your own population?

People kept praising Ben Carson for how brilliant a brain surgeon he was, but I do the same stuff and suddenly the police are trying to arrest me.
