Intrusive ads

This app was fun until ads were introduced. They now delay progress at each stage in an infuriating way.

Is that a bug which brings up an ad for an RPG game? There is no count down, no close icon and no apparent way back to the quiz. The only way out is to the App Store or a force quit of Quizup. The user experience is getting worse and worse.
