If you are a real poster who has had good service from a company, that is fine. If you are a salesman or advertiser butting in to a thread to push your firm or product, you will get deleted and given the bum's rush gently told to push off.
That also applies to those anonymous posters who pop up with weird usernames to gush about a product and then vanish until they come back under a different name to gush again. GNHQ have ways to check their credentials.
