You don't need to delete because you got hacked (whatever that may mean) it just means you should change your passwords on all your logins ...emails, forums, websites, blogs, shopping, etc where necessary!
We can deactivate your account but please be aware duplicate accounts will be deleted (as happened). You are permitted to one account active or inactive only.
This isn't the 'easy' excuse to get a new username. The same rules apply to everyone.
PM me if you would like to be deactivated.
