Hide content and just show ads? What? Who ever suggested anything like that? If other sites are doing this, then they're messing up too. So I've no idea what are you talking about.

They are loading ad impressions that aren't visible. That's a major problem, because it's preventable. Why don't they track scroll –which I'm sure they do already– and load ads accordingly. Their only defense would be that they load the ads, but don't charge for them unless the user scrolls.
