There is no definitive answer to this question, as it is largely up to the PlayStation Network (PSN) to decide whether or not user accounts are deleted after a certain period of time. However, some users have reported that their PlayStation account has been deleted after a short amount of time, while others have said that their account has been deleted without warning. It is important to remember that PSN does not keep track of how many times an account has been used, so it is possible for an account to be deleted multiple times.
