As much as I want to get enough merit to become Hero/Legendary, I disagree with this suggestion. This is the problem for bounty managers, not forum's staffs. If I'm not mistaken, @theymos did consider to separate rank and signature limitation. This separation might be a better solution since Legendary shitposters cannot get benefit from their legacy rank anymore.

I don't like the idea of further discrimination towards newbie and jr. member. Why? Because there are shitposters in every rank and you will drive away good newbies.
