> Why not? I think you missed the point, the plugin or program wouldn't have a distinct pattern or scheme since it would be coming from the website you're visiting. Say, for example, I want to show an ad for denture cream. Nothing fancy, just a gif. Well, the URL would look like http://www.randomsite.com/img/filename.gif http://www.randomsite.com/img/filename.gif How do you block that without blocking every image on the website? Granted, what you propose would be easier to do for more advanced systems, but the key here, is that 95% of adblockers almost exclusively look for calls to ad networks. If you eliminate that, you open up that 95%.
