In order to protect this bulletin board from litigation, in the event that a poster makes a libellous statement, for example, it is a requirement that all posts be moderated.
Currently there are no moderators on PPRuNe that speak and read Chinese and consequently a post in Chinese could not be properly moderated. As a means of legal protection for PPRuNe only and not as an act of discrimination a post in Chinese would be removed. In the event that PPRuNe is able to find Chinese speaking moderators at some time in the future then it is possible that posts in Chinese will then be allowed.
You are, of course, at liberty to establish your own bulletin board and you can specify that the Chinese language may be used, you will be accepting full legal responsibility for anything that appears on such a bulletin board.
Sorry that PPRuNe cannot be more accommodating at this stage, nevertheless, we hope you are able to continue to enjoy this facility which is provided to you completely free of charge.
