Thank you for that detailed reply! I really appreciate it, and I read through all of it. One thing that I forgot to mention were that the some of the ads, if not all, run by the IRA (Internet Research Agency [0]) were veritably false. If Facebook kept score of ads that were known to be false run by an ad buyer couldn't they present that information beside the ad e.g. a sort of running "boy crys wolf" heuristic? Thanks again for your well-researched and extensive reply. [0] https://en.wikipedia.org/wiki/Internet_Research_Agency https://en.wikipedia.org/wiki/Internet_Research_Agency
