I have been careful to maintain the same level of ads and not spam people with pop-ups, etc. I have tried to make the ads somewhat inobtrusive. So I am upset that Google just arbitrarily changed their responsive ad formatting - doubling the size. I just checked and yes, they did so without so much as a request... The MASSIVE ads are being driven by a new feature that allows text ads to be formatted as if they were banner ads - so if you don't have a design team to make fancy banner ads for you, you can enter a few images and text, and Google will do the work for you. However what this creates are MASSIVE ads that, while they look slightly better than text only - are clearly cobbled together using a bunch of random images and graphics. It looks like something a kid in elementary school would do.
