Playing devils advocate, Here's an interesting angle;
If a company can argue to have threads that are critical of it removed, can companies that do not receive praise in the forum also argue that by praising one company, by inference all other companies are implied to be not as good and thus libelled?
But seriously, if a complaint is upheld, then surly referring to it in the forum cannot be deemed to be defamatory or libellous as it is a matter of fact.
