You wrote that users should be active and behave well, and the reward (for example merit points) and good judgement will come automatically. So you could explain why you bought the "Copper Member" rank? After all, the privileges should come naturally.. right?
Well, it's true that doing good will return the favor. Being active doesn't mean the reward will come and that's why the OP bought copper membership. I think the OP is trying to earn merit but failed to earn more and decide to buy copper membership (possibly).
