Why does a website say I have an ad blocker when I don't?

It is incredibly frustrating to visit a website only to be denied access because it accuses you of using an ad blocker you don't even have installed. This usually happens due to network configurations, DNS settings, or the browser's own built-in privacy filters.

The origin of anti-adblock false positives

Websites detect ad blocking when an ad script fails to load. If you use the native tracking protection features in Chrome, Edge, or Firefox, the site interprets this as an ad blocker. AdBlock Network solves this with its Advanced layer: the extension performs asynchronous, read-only requests to multiple independent endpoints to fetch rules, applying perimeter filtering that prevents these false positives from triggering.
