> Another technique used to hide the ad blockers' activities is even more impressive. They are able to "create two copies of the page, one which the user sees (and to which ad-blocking will be applied) and one which the publisher code interacts with, and to ensure that information propagates between these copies in one direction but not the other."
So this ultimate ad-blocker would potentially consume twice as much resources as it would have been?
