Do companies that produce products write consumer reviews?

I am the VP of Content at Viewpoints.com, a consumer reviews site, and in our experience, reputable brands know better than to write reviews under the guise of being a 'real person.' It is pretty easy to catch a fake review and our moderators are trained to spot them a mile away. Those reviews you will never see on Viewpoints. You need to be careful that you get consumer reviews from a reputable site - like anything else, consider the source!
