@bbildman said in Ad Blocking being detected by sites.:
Now that Opera has become so adept at ad-blocking, so have web sites become adept at detecting I am blocking their ads...what now??
Ad blocking involves blocking a browser from retrieving data from a third-party ad server URL. The website code that makes the callout to that URL can readily also perform a handshake with the ad server site to see if the ad has been called... if the handshake doesn't occur, the site knows ad blocking has occurred for that URL, regardless of how the ad server URL was blocked (extension, browser internals, hosts file, etc). It's not rocket science, but merely up to the site as to how it wishes to conduct its business and write its site code (usually employing Javascript for ad callouts). If a site is doing this kind of coding, the only way around it would involve a far more complex blocker code that intercepts and relays only the handshaking data to the browser but blocks any ensuing ads... simple URL black-listing wouldn't cut it. However, once you move into relaying handshaking, the challenges become infinitely more complicated, since there are infinite ways to construct handshakes.
