I was on till like 6 am this morning, and ended up banning a good few for a day which helped. Pretty much shit happens when koreans are on, and most admins are asleep still. I stayed on till I kinda was gonna doze off, but they are koreans enough said. If every little thing is gonna get you mad with that group, then stay off the server or play at regular player times and stop whining. Either contact an admin or personallly mute them, don't waste your time causing a scene spamming your mic against them.
