In the past few days, I've had brief (usually about 1 sec) regular audio outbursts from ads on the site, including when i'm watching videos. It sometimes happens as frequently as every 30 seconds. I've had some other issues with ads randomly auto-playing and persisting after I think I have them paused. I know you have to make money, but this is the most intrusive advertising of all the sites I regularly go to. I normally don't have to go in and try to block individual frames on websites, but I'm at that point.
