Depend on the ad & the company. If it's an annoying pop up, flickering ad or one that makes noise then it gets closed immediately. Then the usually website that generated it gets a nastygram & added to my banned sites list. This only applies to companies that I think are reputable.. .. .Sometimes I get a reply & the website gets changed so I consider it a win. . .. .Obviously if it's the web equivalent of spam or an unknown company it just gets added straight to my restricted sites list.
