I'm not sure. They're blurry so I figure that's the case, unless you've implemented some sort of blurry add campaign or something. You probably have to enlarge the image to see the blurriness.
Yeah I'm not sure. Unless they put in these big bar style ads at the bottom. Mine's all blurry, which is why I figured it's just a small ad from mobile that's auto adjusted to my desktop sized screen.
Running chrome on osx 10.10.5. Forgot to add that in the op.
