Well, thanks for the heads up that the code used to show different ads to different viewports "might" not be compliant with the TOS. Since there's 1000's of sites likely already using the code, seems like the horse has left the gate already on this.
But still, to avoid some algo dumping me off a "you're booted" letter, I removed the code and re-designed things so that the 300x250 ad looks good at all resolutions (although not ideal on mobile devices, obviously).
Perhaps before the onset of the next Ice Age the Adsense people will release some responsive optimized ads for general use. But admittedly, I won't be holding my breath on that one.
