They removed some today, but left some obvious speedhackers still in it. Not to mention they removed some characters from an account, but left 4+ of their alts in the leaderboard.
They also likely werent rankbanned, cuz you see them still in other rankings meaning alot prolly gonna enter today and hack again.
Im not sure if there already was a race and alot of em reentered today, but thats possible too.
