Text advertisements are cheap, bandwidth-wise. I wonder if they couldn't just send everybody dozens of advertisements, and decide on the client side what to show. Or even, download a dozens of MBs of graphical ads with each app update / the first time you visit the site.
You could go further and do something like, email sent by people to people is off-limits and will be end-to-end encrypted and not looked at - but (almost) all automatically generated email is fair game and will be processed. Google already does that with Google Now (and shows you your flights, package deliveries etc.). I really prefer them making more explicit what they look at and what not.

Shh, don't tell everyone about my next project. I think it can be done with images as well sending 5 of them for various demographic groups would be doable and should create enough noise (one tampon ad, a video game ad, an ad for amazon, a mountain dew ad, and a retirement plan ad for example). For those who care not for anonymity, but more for bandwidth they can opt out and only download the ad's they need.
