I'm sure most of you will remember the recent thread in here about a traffic provider, this isn't a continuation of that thread but to address a question i gave that provider about having a site in a popup and how it would affect adsense. That particular provider argued that seeing as it was fullscreen there would be no problem.
I contacted google and after a few emails back and forth, a lost one due to system changes, they have informed me on what grounds adsense could appear in a popup:
:- if it in no way whatsoever interferes with navigation
:- if the "fullscreen popup" window has the address bar and the address in it - this way seeing as it's fullscreen it will be considered a new window and not a popup
If there is no address bar then you risk having your adsense account disabled, if it interferes with a users navigation - the site they are visiting or is not easy to close then you also risk losing your adsense account.
Just a heads up for those of you that have adsense and use traffic providers that use popups
