yes, but it will have to operate outside the DOM. currently adblock killer/detection scripts relies on the fact that resources/scripts fail to load (both can be detected), or an element isn't showing (the nag message is hidden under the place where the ad should be). if your browser is dutifully rendering the ads as intended, but blocks it out in the frame buffer, there's nothing the site can do. no such adblocker exists as of yet.
