BUT, if you translate the regulation itself (http://www.cac.gov.cn/2017-08/25/c_1121541921.htm) it does appear that it outlaws forum posts by anonymous users:
These Provisions shall apply to the Internet forums within the territory of the People 's Republic of China. The term "Internet forum community service" as mentioned in these Provisions refers to the provision of interactive information publishing community platform in the form of forums, postings, communities and so on.
then
Article 8 Internet forum community service providers shall, in accordance with the principle of "backstage real name and front desk voluntarily", require the user to register the account through the authentication of the authenticity information and carry out the verification of the true identity information of the sponsor and the manager. Users do not provide real identity information, Internet forum community service providers shall not provide information dissemination services.
So yes, this does seem to require real name verification for forums.
(Also, Google Translate is a miracle of the age)
