The following information was sourced from Sony’s (US/America) official “Knowledge Centre” FAQ.
When I contacted my local Australian PSN Support they flat out told me they could not delete PSN accounts. I will chase them up because it seems that someone somewhere has the power to “terminate” accounts!
Be careful though — it is not clear if an account termination would free up the sign-in email address or online ID (probably not).
