Re: [Merit Analysis] Users ranked Sr. Member & up that have not earned any merit
You know what is more interesting? Demoting them back to newbie 
I wouldn't go that far... They hanged on here for years and raised the activity. That has to be worth something.Demoting them back to the newbies by just simply disregarding the activity they achieved through their career is not an option too.
What I think is the answer is laying between above two options. How about if we implement a system for trigger( having opptunity to award merits)the airdrop merits only when a user earned some predefined merits. By that way we can reduse most of the merit abuse cases where users tends to giving away merits for their alt accounts.
Any user that has never sent nor received sMerit is not in the UserData table, which is likely the majority of cases that you are looking for.
So my point is that you are listing a different set of users to the intended objective (a subset really).
I don't know why people are so worrying and anylizing about the never sent portion since it's nothing to do with the number of users ranked Sr. Members & up that have not earned any merit. Why we just couldn't consider the received sMerits part only because I have seen that some members still didn't shared their intial airdrop merits at least once.So my point is that you are listing a different set of users to the intended objective (a subset really).
