This is jmfcst's second duplicate account. Dave's policy was always to ban posters on the basis of having a duplicate account. I do not understand Inks/Nym's reasoning here of implimenting this now (and therefore allowing an exception to me made) when in fact it has always been the policy of the Forum.
As we've been over this has always been for people circumventing bans or running duplicate accounts simultaneously.
I can't think of a precedent where people have left voluntarily and then been banned on returning with a new account.
