I just quickly gone through with merit dashboard and found out that there are 44 Hero members still didn't sent any sMerit from their initial airdrop of 1000 Merits and also there are 44.133 Merits (around 22K sMerits) hoarding by those 44 Hero Members alone.
The airdrop was 500 for 95% of the Hero members, not 1000, and i'm pretty sure the sMerit that was received from the airdrop was absolutely
not a 2:1 ratio. (So 500 Merit ≠ 250 sMerit.) It was wayy less.
