User blog comment:Adam Carey/Making Ads Better: What We've Done So Far/@comment-2763-20170119064419

I like what I understand you're trying to do. I hope you can gradually eliminate the chance that we might see an ad that takes over the background and has a banner four or more times the standard size so that less than two lines of page content is visible!

Is it really still impossible at present for you to set an absolute limit to the amount of screen an ad can take up?
