Why don't you just set it up so the prevention usergroup is "banned" usergroup. That way, any alt (account B) is automatically banned.

This would NOT ban the original account.(Account A) But you would get a PM and/or a thread made, allowing you to manually ban the original account.

If you ban the original account, and the user tries to make another account (Account C), he/she would automatically be banned.

You can do all of that with the built in features.

As for users clearing cookies, using different browsers, or IP addresses, there's nothing Kiros or anyone can do about that. (AFAIK)
