There's also the tactic where the layout of the page/app reflows after a second or two, changing where the ads are. It drives me up the wall. Go to tap on a button, SURPRISE, an ad popped in where the button used to be 10ms before you touched the screen and now you're forced into some company's site whether you wanted to see it or not.

This is my biggest frustration with ads. It will surely cause fake statistics for ad campaigns too: 99% of time when I click ad, it is by mistake.
