I fully support Brett's decision. I think it needs to go one step further and the reference to "The camper that shall not be named" should be removed from signature lines, avatars and profiles. If this particular company wishes to be annonimous, then a complete removal of reference from forums will do more damage to their business than having negative comments posted.
When I am researching a product I google it, generally if the only response I find is advertising, then I have some alarm bells ring.
I think the smart way for this company to improve their reputation would be to improve quality and customer service, not bully their customers to only say good about them.
