Just recently many people have been duping in the game Sephiroth which is the korean version of turf battles, this has lead to smilegate shutting off registrations and trades and warehouses in the game. You now need to have a korean phone number so they can call you to confirm your details.
they will also send you a text if you have a mobile, once again you MUST be korean to register.

Remember keep sending those emails off to smilegate asking to bring the game back.
