Hilarious. Two of those wallets are mine, although I never did use either of them. Downloaded one and it required an update before I used it and I did not want to mess with it so deleted it and made another, which might have been usable for a day or two until the next fuckfork came along. At any rate the coins I mined I just sent straight to exchange and never did use an XPY wallet. So they can subtract two wallets right there. I bet a LOT of them are just ghost wallets like mine.
They won't show on that list unless they hold coins IIRC.
