Advertisements in apps that open automatically?
So this morning I thought I accidentally clicked on an ad in the ask.fm app (it's a legit app) and the ad redirected to this app called "Game of War" in the appstore. I didn't download anything and I closed the appstore. Just to be sure, I reset my iPhone and restored it to an earlier backup. A few minutes ago I received a notification that I had a new ask, so I opened the ask.fm app to answer it. Without touching the advertisement banner (I'm more than 101% sure that I didn't touch it cause I opened the app and put my iPhone down on the chair beside me) the ad automatically redirected back to this "Game of War" app in the appstore. How is this possible?
