unbanned or not?

Yesterday maple administrator(the npc) talked to me while i was training. His mesaage was: you have been banned from maplestory for hacking(i never hacked in my whole life and never exploited bugs). Then i disconnected and i couldn't logg into the game anymore. One hour after, i was unbanned. Very strange. Anyone has seen this problem?

off topic but, that is the autoban message, its a work in progress for nexon, it does do the false positive thing quite a bit.
