To be fair.. let's demoted 2 rank to all ranks so they must reach their Merit to get their previous ranks before the system update.
But I still can't find a way to prevent spammer/shitposter/famer with this method alone.
Oh yes this will become CHAOS for the impact of new system has reached to everyone without exceptions :3.
Legendary become Sr.Member, Hero become full member and Sr.member become member and so on.
So the system will be accepted without any rejection in unfairness method that happened.

Or... Have you read about these suggestion?
Suggestion 1 and Suggestion 2
Give me your comment about these please :3.
