Also Bijou is jumping the gun, or thinking Kao isn't doing his job becuase Kao loves to kill socks,and it would be kind of hard to make a sock with premium without having questions come up as to why 2 account have the same name on the pay stub. (I haven't signed up for prem so I don't know if there is an anonymous way to do it.)
It's more common than you think. There are like five or six banned accounts with my name on them from when I bought premium for participants/winners in the WoW Halloween story contests.
It's funny that we can do that to each other considering we have the same permission level. You'd think it'd be grayed out like it is when attempting to edit an Administrator.
If it's anything like it is around here(or was, not sure if still the same way since I'm working on purely inferred information based on how things have been reported to have played out), you might also be able to ban yourself.
