this will be a nice idea but I don't think it's going to help because people are active in the forum to share their ideas with others on the crypto space and at the same time we are all here to improve too, people like to progress in anything they do and when they don't they forget about it. And you know, if we divide the accounts on this forum into four parts I'm sure that roughly one part of the accounts here normally earn merits in each post. And if in the future people also see that their ranks are decreasing many will leave the forum and the forum might lose it traffic too. Just like what happened when mixer was banned, some people left the forum.
(I haven't managed to state things exactly how I would have liked, but, my wife is shouting at me from across the house to come and eat, so, I'm going to stop fussing this post now and go get some chow.) 
Enjoy your meal
