Why does Opera's built-in blocker let ads through?

Many Opera users find it frustrating when the native ad blocker lets video ads slip through on popular sites or displays specific sponsored banners on search engines.

Built-in blockers often operate under corporate deals to permit 'acceptable ads'. AdBlock Network is completely independent. Our extension performs read-only, asynchronous requests to multiple independent endpoints to update your firewall, ensuring that blocking at the Address layer remains free from commercial compromise.
