SEA Arbitrage?

Saw this today:



Landing Page:



It seems like a kind of search advertising arbitrage play. Is this whitehat? I would expect Google to not allow something like this. Especially since the landing page uses google custom search for monetization?! Anyone have any information, resources, guides, or experience on this type of strategy? Whats it called?

Thanks,

perfectly fine. Visymo is a google partner and run a lot of these websites.
