Google appears to be starting to crackdown on these methods, but perhaps I've just been unlucky and got a manual reviewer in a bad mood.

I've put a workaround, which would be to create an onclick popup with an URL pointed to a script located in my own site. This script checks if the user is mobile, which would get him redirected to Plugrush's direct mobile URL. Otherwise, I show him a large plug grid.

Hope it helps.
