The reason why alternative accounts on the same server is frowned upon is because they are normally used to benefit the main account. However, having *ternate account is not a bannable offense, it is abusing it to benefit your main account that is bannable. It is not the act of having *ternative account, but the intentions behind it that results in potential consequences.

Terribly sorry for the confusion and I hope that clears things up.
