No, once a username is closed, it is retired & can never be used by someone else. Your username is yours alone & yours ALONE. When you retire, your office badge number is retired & can never be used by someone else. Same deal. Using someone else's name is considered fraud & illegal.
If You Close A Gmail Account, Can Someone Else Sign Up For Gmail With The Username That Was Previously Closed?
No. None of these sites recycle usernames. They make you chose another one,
No, it's forbidden the account under that name becomes delinquent
No you can't they'll just say that this email is already taken so yea!
No. Even with you Internet Provider, should you close your account, that name can never be used as an email name again.
Only if you (or anyone else) closes the account officialy!!
Yes I suppose so seeing as it's no longer in use the name should become available
