I don't think it is a case of they don't care, more of a fact they just can't stop it or control it in any way. K2 have always run KO on a get rich quick style. Very little resources are put into KO compaired to the other MMORPG's that are popular on the net today. Because of this you find when they get a really good person ( and lets face it they have had a fair number of really good and passionate people supporting the gamers over the years ) they get sick of not having the resources or tools to do their job properly and in the end loose faith in the whole system.
As long as they are making a good margin of profit for very little time and money the situation in KO will always remains the same.
