As Nutcutlet has said - there's a huge difference between a personal recommendation based on the experience of a forum member, and the attempts by some companies to post advertisements without paying the website.
As far as I'm aware, there's never been a problem with posting personal recommendations.
I'm sure the GW team would let us know if there was.
After all, if mentioning trade names was forbidden, it would mean that the Original Poster would have to change his name and that would never do!
