But why wouldn't the ad broker engage in a sibyl attack? It's in
his economic interest to know EXACTLY who's getting his ads, because
that list of names/addresses is one of the things he sells. In this
era the consumer IS the product.
Heck, he'll even serve up ads that prompt internet requests to his
own servers to get one-pixel graphics just to see where the requests
come from, if we don't give him an easier way to find out.
