This is just a question that me and my wife are wondering . If you get banned from the game how long would you have to wait to get back in . Or would you have to make a new account?
As I understand it, a ban hits at the IP level. Not just your account but your computer itself is banned.
Whatever someone might do that is so terrible as to make KI ban them completely (remove their account) and forego all revenue forevermore from that person ... is something that makes them never want to deal with that person again. So they do what they can to make it really difficult for that person to ever get back into the game again.
There are two different types of bans: an IP ban and just a normal ban. If your account had been banned normally then you should be able to just make a new account and continue playing. However, if you have been affected by an IP ban this means that you will be unable to make a new account under that IP address.
