Re: running ads. Locally. Without tracking me
Realistically all you can do is block ad site cookies to defend against this. The ad site has to serve the ad or they aren't paying the host site. So your browser has to request an asset from the ad site and send all the browser footprint info it normally does. They can't track you directly but they know your source ip, user agent and a whole load of other stuff.
There is no way anyone is paying a site owner lots of cash because they promise on their life that they definitely served loads of ads to people.
