As for the former, I'm pretty sure I'd trigger as robot since I use keyboard mostly (using some special features in Firefox) just because they make it a lot faster and nicer.
As for the latter, iirc there are blur/focus(-like) events for the window object. Maybe mouse movements gives them better confidence? Because of course you want to make absolutely sure your users are seeing all the ads.
