Even the numbers that come from square... well, you can say they're accurate, but they're useless. Since they count all characters ever in their official census. Which these stat sites also do with just as much accuracy, but then they track extra stuff (with less accuracy, but far from useless).
Like another poster said, Square will never give us useful info, because 9+ million registrations/characters sounds a lot better than "about 600k active subs".
