It seems to me that the root if this is having a sub forum called *Off-Topic* . Since it is not dedicated to discussions related to any of the topics we can find in General, Daoist etc. people will identify it as total freedom space.
So even if you put in bold, in capital letters,in an audio file that **forum rules apply** some people won't hear that because they will immediately feel that it is censorship, whatever grounds you give to the rules.
And when it comes to politics, it just becomes totally wild and out of control We can see so called spiritual seekers turning into completely polarized internet beasts and it becomes impossible and pointless to discuss with them.
Just like people in TDB who want to show that their school can pee way farther than any other.
One can notice that those kind of battles are always conducted in the name of *truth* ( hey, I am of this X school and in the name of Truth I can let people say this or that etc.), *freedom* (In the name of truth and freedom of speech, I must say this and that and the Admin can't muzzle me etc. otherwise the admin is just another a*****ole), and the same for *justice* etc.
You know it is perhaps and probably just me but one reason I wanted to learn more about Lao-Tzu and Zhuang Zi was that they found no real meaning in all this worldy and petty matters. The world is full of ugliness, not because it is its intrinsic quality but because people bring their ugly minds and actions in it. As soon as one diminishes all worldly desires, the environment around becomes a more peaceful place. I have really, really, really hard time to see how being involved in politics (and heart/mind is the root of any involvement as far as I can see) can bring any peace internally and externally. What politics did Daoists in the mountains and in caves, Christians in the deserts, Buddhists in their forest or caves?
Anyway, the only solution to this recurrent situation at TDB may be to close the off topic section. At least, it will limit the problems to Mopai etc. which is enough to keep the mods busy.
