In my opinion, this is an April Fools joke from admin. April Fools is a wide known tradition in this world, and i believe it is known globally, not only in one country, but if this system is true, i will be shocked hard.
I don't think it is entirely global which accounts partly for the large number of people not getting it. Then there are those who will always be fooled. I'm enjoying how many are asking what the f in fMerit stands for
Another plus signal is I have not seen Theymos launched something without detailed announcement about its mechanism.
Combined all of them, I believe we have witnessed big joke.
Congratulations, take it easy and enjoy fun.
Oh, there's a detailed announcement and full instructions to calculate if you will rank up. https://bitcointalk.org/index.php?topic=3232693.0
I was so confused, came back after a short hiatus and saw Karma and politeness, I guess Theymos has had enough of the crazy ALL CAPS color trolls - I think I like this new change
Edit: nvm, as soon as I posted it went back to the old, got me for sure
