There have been Koreans here since wemade. They're actually pretty respectful as they really did only join their own rooms. They also joined farms. The two Korean players that were in wemade are still active today and are both Colonel rank.
Their names are Minerva and Munchie.
Like I said before though, I actually don't mind these people because they literally never speak and they typically battle or farm together. I honestly wouldn't mind if the whole foreigner population was removed and they still stayed.
Why they want to play our version when they have the superior one beats me.
