It seems KOG uses the BOARD to investigate cheaters . Tested on 3 accounts, 2 of them regularly use the board to sell materials and trade ED and got Banned after 2 or 3 updates due to "Botting". The other one doesn't use the board and is still safe so far. It's quite difficult not being able to use the board to sell materials, most EDs are earned from selling materials on the board.
