That's my take. They kicked it up a notch from human execution to computerized execution of the models they were collecting before. Their models might be better, too.
Map out exactly what the voter wants to hear, bury your message inside a wrapper of fake news that speaks directly to them.
The part that makes it so insidious, is that ad targeting is so fine grained, that only the victim will be able to see the ads, it is an imperceptible enemy. Literally zero rebuttals given.
Really hard to prove attribution. The assumption that the election was won because everyone who didnt vote like you was "manipulated" is insulting. We're all just getting more entrenched.
As for shell accounts, tinfoil hat is all I'm hearing. Prove it. There is more substance in DNC leaked emails than any of this left conspiracy nonsense.
Edit: wtf is fraud laundering?
Facebook absolutely has a log of every ad shown to every user, ever. Who bought the impression and who viewed it.
