As long as a ban is imposed fairly according to the rules, it is then acceptable. However, I know of one other forum that has banned a person because of his legitimate & realistic comments, because 3 others disagreed with the person's opinions. This led to all sorts of silly queries that the moderator intervened by imposing an unjustifiable 3-day ban on the person concerned, with vague/incomprehensible reasons given. It appeared some sort of a "ganging-up" had occured. The bias & lack professionalism only make people leave such a forum without any regret. Glad that Sino-Defence remains a professional forum to date.
