It's like a dialog box pop up that says I won an iPhone and then when I click ok it takes me to some site with a roulette wheel. Mobile btw If you're on an android phone, you can always hit the back button to get rid of any popup. If you're on an iphone, well, iphones suck. But I neither of the ad services I'm using should be set up for popup ads on mobile or desktop. I am looking at the board using safari on an iPhone 6 and have been hammered with pop ups today.
