I have an Android app which, in free version, has an ad block at the top of the screen. Of course users can see ads only if they're connected to internet. If they are not connected they get the same screen size as PRO users which is kind of a cheating :)

So, now, I'm in a dilemma: should I make the place where ads are always show and, in case if there is no internet connection, display only black empty space - or the other option, to leave it be and let the user experience "full screen" even if they hadn't purchased the Pro version?
