To add a bit more into your information the appearance of ads from the end user perspective is random (3) and (4) could not be done automatically, because you'd have to know the exact moment the relevant ad was to appear. Serving the ads is automated à la Google auction technique so unpredictable. The only way to spoof that is to expand the targeted audience. The automated ad clicks that I refer to is demonstrated by a gaping hole in the data consistency, which would not otherwise occur if the action was taking place outside of Facebook's own servers.
