there no way to detect sold accounts and they never strict on this things i remember few years ago everyone scripting on IWZ and they dont care, even played with VPN on by mistake and logged in from diff country too , they have 0 proof if some1 sell their account if nobody ticket or something bout that..
and i tried DMM FKG but rates seems lower than Nutaku and u waste too much time in DMM coz no auto mode, the only thing that keep me to play FKG for 2 years + was that it doesn't ate me much time and i have time for other games.
