Yep, banners that cross horizontally across the screen. I have a minimal amount of ad blockers on safari and far more on Chrome. It's interesting but some sites simply don't work well at all on Safari, irrespective of the ads. And other sites are so cluttered with ads, pop-ups and garbage, that I simply avoid them or paste the URL into the Chrome browser, where the heavy duty blockers mitigate them.
There's gotta be a better way to monetize without interfering with readability.
