Philosophical Design Change
Devise a two layer design for Ad Blocker. Think of it as a two way mirror.
From the web viewpoint, a browser with Ad Blocker looks like any normal browser. From the back side of the mirror only the non ads are brought to the visible surface. Or the real content is brought through to the visible browser window.
There are so many sites that come up with, "We've noticed that you're using an Ad Blocker" while at the same time the blocked ads counter is spinning like a slot machine reel. There are some sites that try to display 50 or 60 ads in a minute and a half.
