Were the metrics related to the company in your profile? It seems legit(and a good idea even!) but I can see how that data might end up looking like spammer/blackhat SEO data to a robot.
I think, perhaps, the 404 you got was not for your file, but just a broken link to their review form. Is there some other manner you can find a different review button? This[0] implies you can click Share -> Request a Review, maybe try that?
