Somebody else in my family wants an account and because I have been banned I don't want to play anymore. Can I exit my account and let him play as a different one?
a) you haven't been banned, otherwise you couldn't log in anymore
b) no, you cannot give your account to someone else. If you don't want to play anymore and want to have a family member play, that family member will have to create a new account and sign up as your multi. Otherwise, both accounts will be banned.
