On my local board, I keep track of this forum wide, in a thread I update monthly (see sMerit - Generosos y Tacaños - Foro Español). Although I focus on the Spanish local board, the Google Doc in my post contains a tab called "Foro Global" where data for all merited profiles is available, and with a filter by sMeritGenerated and ordering by %sMeritsSent you can obtain a global view of that depicted in the OP here. Of course, airdropped sMerits and Merits Source sMerits are not deal with there.

On my local board, there are some profiles that are not too proliferating when it comes to sending sMerits (despite earning a fair share), but I much prefer their contributions through their posts than anything else, and if they don’t want to participate in the Merit System, then that’s their prerogative really.
