Ah ok Brain. In that case you should be right though... You should have notified Fizzer earlier though:
VII. WarLight Accounts
In order to access some features of the Service, you will have to create a WarLight Account. Users are restricted from use of another's Users Account without permission. Users are restricted from impersonating another User's Account. When creating a User Account, you must provide accurate and complete information. Users are solely responsible for the activity that occurs on User Account, and Users must keep Account password secure. You must notify WarLight, LLC. immediately of any breach of security or unauthorized use of a User Account.
Unfortunately all you can do (that I'm aware of) is wait out the ban then change your password. Unless you can prove it wasn't you who merited the ban (not sure how you could do that... IP Addresses? Not conclusive either :/).
