We strive for open and informed debate, but unfortunately, this forum also has legal obligations and restrictions. Because defamation laws differ in the various markets we reach, we need to adopt a "lowest common denominator" approach and err on the side of cuation. This is not only for out protection, but also to prevent posters from being sued.
Please bear in mind that the removal of threads or their closure does not automatically mean the content is true - or false. And remember also that truth alone is no defence against defamation action.
