i said: the leader boards of zones scores are messed up, broken, bugged or whatever you like to call it. those are not cheaters.
they havent managed to be at the top, they didnt hack something...it's just a coincidence because LBoards doesnt works, the raking looks like are randomly placed.
back in the days there was a glitch on anulpha pass that did let you reach incredible\not human zone scores, but this was patched in latest version of the game.
it's a bug. deal with it.
for a better raking consultation\update just check wipeoutrankings.com, still a better choice
