Fun fact: prior to my joining this wonderful Staff team, I too had to make it known that my wife intended to create an account completely separate from mine.
This is nothing more than yet another unfortunate case of a new member failing to review our Community Guidelines (it's the first rule listed even). Our Guidelines also note that you can contact Staff for information on creating multiple accounts for family members and/or spouses. It's not our job to essentially read minds and know why a user is creating duplicate accounts. Your irresponsibility led to the banning of your other four accounts (and likely this one as well).
Also, I wanted to clarify something:
Never share an account with another person, whatever the case. If you belong to a household with multiple aspiring webmasters / developers, it's fine if you download something and send it to them over your own network. We cannot control that. But allowing another user to use your account is prohibited. This is for your own protection. If someone else violates our Guidelines while using your account, you are responsible for their actions and the subsequent penalty for those actions. This is also why we encourage users to contact our team if you're in need of another account for your husband/wife or children. It takes you less time to send out a PM, than it does for you to create a dummy email to circumvent a suspension for being a bonehead.
