Yelp extorting small businesses

I visited the site in incognito mode, and I see the review: <a href="http://i.imgur.com/v9P9cJJ.png" rel="nofollow">http://i.imgur.com/v9P9cJJ.png</a><p>Yelp has publicly stated that they filter reviews[0] since many people try to game the system. I'm not sure how they filter the reviews, but this is probably a good guess: <a href="http://qr.ae/TluW1" rel="nofollow">http://qr.ae/TluW1</a><p><i>Disclaimer: I'll be interning at Yelp over the summer.</i><p>[0]: <a href="http://qr.ae/TluOB" rel="nofollow">http://qr.ae/TluOB</a>

Is anyone surprised? This has been going on for YEARS now, but the users think they are getting what they want. It's the business owners that get the short end of the stick.
