Sorry, I'm not sure what you're referring to. Brave has 2 ad-models (one still in the works). First, the User Model. In this model, user's must first opt-in to participate. If/when they do, advertisements are shown (at a user-controllable rate) as OS notifications. When a notification is shown, 70% of the revenue is deposited into the user's wallet.
The second model is the Publisher Model; this is in the works now. Under this model, Publishers will be able to opt-in the system as well, and have ads displayed on their pages. Under this model, publishers receive 70%, and the user receives 15%. But both models require consent before any ads are displayed.
