Perhaps halloween event, Bifrost, Who knows K2 doesnt tell us too much 3 maintenance in 3 days k2 going for a record ? Maybe its new server (ROFL JK). Most likely its to block some other words from chat such as lame, dung, poop and K2/GM etc that way they can be flammed ..... even more
Today our servers will be coming down for special maintenance for a duration of approximately one hour. During an after the maintenance, portions of the Power Up Store affected by GamersFirst (such as the Elite Club for purchasing Premium and recharging your G1 Credits) will also be unavailable for a longer period of time. Thanks for your patience!
-the Knight Online team
Edit: GM is already blocked
