I've only been aware of one, but that was when they were dealing with a chinese gold farmer. It seems the rollbacks/bans have eased off for RWTing (friend got banned for gold farming few days ago) but with that being said, still be careful.
Yes,i experinced it yesterday,My two member accounts got rollback yesterday ,and i lost 1.5B,meanwhile one of my non member account got banned which has 106M in bank
Friend of mine got RWT major a few hours ago, sold 1b to a guy, he is also banned. I dont know if using a VPN or Proxy would help? They trace the Ip's of mules, so why dont we just un connect the mules..I throw mine away after 2-3 trades.
I'm running a small goldfarm at the moment heavily, and not one account has been rolled back. I also run each account on a separate IP address with my mules attached to a different IP.
