do k2 punish themself because they disrupt someones game play experience?Dear Knight Online Players, *
Today, on October 20, 2006, our Knight Online team has suspended more accounts that were identified exploiting the quest bug or found to be using a 3rd party program. We can assure you that in efforts to make Knight Online better and more fun for all players, we will continue to punish those who disrupt others game play experience.
