Lesson 4 of 5
Anti-adblock walls
Why some sites detect blockers and how good blockers respond.
5 min read
Publishers sometimes inject scripts that detect ad blockers and either nag you or hide the article. These detectors look for missing ad elements, blocked scripts or specific globals.
Mature filter lists include anti-anti-adblock rules that neutralise common detectors. NovaBlock applies these automatically; you usually don't have to do anything.
Key takeaways
- Anti-adblock scripts test for missing ad slots.
- Anti-anti-adblock rules counter the detectors.
- Some publishers ratchet up the arms race; community lists usually catch up within days.
