Another policy, which I am not sure if it applies to the place the above mentioned propaganda had taken place–中文 channel, one of the Player Created Language Channels

Off Topic (OT) discussions and casual conversation should be kept to a minimum. In order for questions and information to be relayed more efficiently and in a timely manner, channel patrons are asked to refrain from using these channels to socialize, particularly during peak hours. We also request that certain topics (religion and politics, especially) be avoided. Inevitably, conversations of this nature have a tendency to result in heated arguments and flaming. Please use common sense when discussing OT themes and be considerate of others.
