Project idea

I don't know much about how ad networks run, but if they're targeted then those companies should give you some way to control it, right? That can be repurposed to show the common user what all is being tracked. Eg: I put an ad which targets based on location, say, "prefer people in India". And the ad text is something like, "You're in India, aren't you? This ad was aimed at you because of that. Companies like Google and Facebook may be tracking your location. Go to {some helpful website} to find out how to stop this." Of course, this could easily be interpreted as marketing for VPNs etc.
