I would say that is likely true, I have not yet played this game but I am downloading it. In my experience with runescape the game is also overloaded with people using macro's to level/gain items to sell for gp, as well as accounts. Jagex has attempted and recently added an update that they say will ban all people who real life trade. I would think in an online game as popular as KO that they would be able to prevent duping. They know the code they can't be so unknowning of the game they wrote to prevent the cheats from being availiable. 
Also this article should include information on the experience leveling system, such as how much exp it takes to level. Not just that there is not enough information on the p2p pay to play cost, and I think that would be a good addition to this page as well.
