Yeah, those are super-obnoxious, and frankly user-hostile. I'm not sure why advertisers don't consider that click-fraud.

I was on some page the other day that had a popover ad that looked kind of like this:

  B B B B B B B B B B
  B B C C C C C C B B
  B B C C C C C C B B
  B B A A A A A A B B
  B B A A A A A A B B
  B B C C C C C C B B
  B B C C C C C C B B
  B B C C C C C C B B
  B B B B B B B B B B

Here the elements are Ad, Background, and Content. Everything except the content was treated as click target for the content.
