Wouldn't this require access to bid side data? The OP mentions it's pretty easy to get, but any company using this to expose advertisers is going to get their access cut off pretty fast. As the saying goes, "snitches get stitches".
My thought here is that there is likely a lot of leaked data on ads themselves, that is one of the reasons why you would need the VPN/proxy. Additionally you could (potentially) create fake browser fingerprint credentials on the fly to feed sites and have the VPN/proxy track the ads that show up for those credentials. (other credentials like email and the like could also be created by the app for you) You don't see the bid data, but you may be able to control the tracking that spurs it and you can see the results of it so a setup like this could likely make some inferences.
I don't know this industry well and the tech here has long sense eclipsed me so I really don't know what is possible but I imagine there are possibilities with this setup.
