In the past, the deletion of a Twitter account was permanent and not only that but you will also be unable to use the email account that you have tied to your deleted Twitter account. Now things in Twitter have slightly changed and you actually have a chance to recover your deleted account.
Even with a warning some people deactivate their accounts.
So if, for whatever reason, you found that your Twitter account has been deleted; whether it was a vengeful ex, a hacker or a fit of rage, you have 6 months before your account is permanently deleted.
