You can't ban discussion of politics and have a viable discussion site. The root of politics is "polis", the community. It's very closely related to the word "policy". Politics is life and life is politics. People who want to ban political discussion merely want to ban politics that they, personally, have not internalized to the point where they no longer think about it.The thing is, you CAN'T ban discussion of politics and still have a viable rpg discussion site.
