Oh, wait. @BruhLight and @Mattches that might make sense based on the screenshot shared. That ad is talking about Web Discovery Project for Brave. You can see that it says go to configurations and opt for web discovery project. So clicking on that ad did exactly what it mentioned, which is to open the settings so they could opt in to Web Discovery Project.
Other thing I want to advise you on is that you don’t need to click on ads to earn BAT or anything. Only click on ads if you’re seeing them and are interested.
