Understandable if it is a manufactures website, as they do not wish to promote the competition, however, for a general website, it is a ridicules’ rule.

If on the other hand, it is a manufacture or dealer etc. that is using the forum to promote their wares, as if they were a member of the general public, then that is a different thing altogether, particularly as most sites allow manufactures & dealers to post, so long as the inform the users that they are a manufacture or dealer.
