Yes, ads that break frames are against the terms of the site. It's mentioned in the site's TOS, advertising terms #4 "Your website must not contain any frame breakers". These ads usually get rejected by most admins. These ads "break" the timer bar taking all over the screen and so the user who clicked will not be able to choose the "matching icons" and therefore will not get credited.
I didn't see any rejected ad that you posted today. I can check it for you, just send the link for the ad to my email.
