I particularly felt Anandtech was a particularly bad example of an advertising supported site because, more than any other site, when I was browsing it in my iPad I would try to click on a link and it seemed almost every time the layout would shift and KA-CHING I’d click on an ad accidentally.

Maybe it is just paranoia, they never asked permission to access the accelerometer, but it happened so consistently I wondered if they had something that would detect the motion that comes before a click and shifted the layout deliberately.
