Disclosure; I graduated from Hack Reactor in October 2013.

The lack of negative reviews may seem strange, but I genuinely believe that everyone who has written about HR does so in a sincere manner (whether it be positive or negative). I can understand how it seems shady, but with a $17k tuition, a "free" hoodie is not enough to sway a review one way or the other.

That's intuitive but factually incorrect. There's a large body of empirical research that shows that giving away trivial tokens has a significant impact. This is true for everything from charitable donations to sign-ups for services to survey responses. Not to mention ratings for college courses, which are, in the aggregate, more expensive than Hack Reactor.

I'm past the edit window here, but it's also not to the point. The point is that, by incentivizing reviews, you skew the sample of reviewers. Even if we didn't have decades of research showing that giving people toys changes their behavior, it would still change the sample of reviewers and make the rating both meaningless and misleading.
