The Better Business Bureau is a Scam in Itself

Yelp is just as bad. Here's a recent story explaining that they essentially do the same thing as BBB with constant harrassment of business owners to advertise, and for those who do not, good reviews get hidden.
On a Quest to Be Yelp's Worst Restaurant - ABC News

It does not entirely escape suspicion that it is an ingenious marketing ploy for a restaurant that, perhaps, truly did earn some lower reviews by way of a few bad meals or service experiences. On the other hand, a family friend is a small business owner and commented that he is regularly bombarded with their insistence that he pay for advertising and, as a business that just started and is short spare capital for such things, he's declined and coincidentally seen some of his good reviews mysteriously filter out once he did (from reviewers with more than a few reviews, not just new accounts). I've heard that groups that do pay for advertising see their bad reviews filtered more often than not. That wacky algorithm seems largely driven by the cash deposited, and that defeats the purpose of what most users believe the site is supposed to be.

TLDR - Yelp is just as bad. The only saving grace is that users who are aware of their greasy advertising racket can go the extra mile of seeking out the filtered responses, because that is often where you'll find some of the more accurate viewpoints.
