There's a javascript out there that puts popups on a delay. You can hit the popup javascript on "whateversite.com" and never see any indication of it until you have left the site and are already searching a different site. Could even be delayed up to 10 or 20 minutes from the time you loaded the script.
So this would easiy make it seem like it wasn't their site that popped up the consoles, but the site you were currently browsing at the time the delay went off.
