As of September, there have been 322 Legendary who have received merit with a total of 6.814. Isn't that a pretty high number?
There are an average of 420 Legendary during this year who have earned merits every month (excluding September), but if you want to know the full data, please visit the merit dashboard.
Can you get the data of how many legendary members were active this year and haven't got any merits? I think there were not only 420 high-ranking members in the forum so what happens to the rest of the accounts? They are stolen accounts of the ownership of those accounts been changed?
Accounts that got merits in airdropped and inactive for a long time should erase their merits. Many of those accounts end up being in the account seller's hands.
