When you go to the page, you're served a full page ad, and you have to move your mouse to the right in order to get the actual article to move left in order for you to read it.

As far as UX goes, this is about as bad as you get to force people to view an ad.

I'm a developer and it took me a few seconds to realize what was happening. I'm fairly certain most users would go to the page, see the ad and think, "Where's the article I just clicked on?" not see it and then leave right away.
