Holding period for cancelled account domains
When an account is terminated and a domain remains actively registered and with the same authoritative nameservers, there is nothing stopping other users on same server or DNS cluster from parking this domain onto their account, thus obtaining the ability to put up their own site and control emails for this domain.
A classic example of this is where a business ceases trading, their hosting account falls into arrears and is cancelled (terminated). This would open up the possibility that an imposter with an account in the same DNS trust could park the domain and take control of the business website and email, leading to many avenues of abuse taking place.
I propose a holding period option, where terminated domains are not available for addon/parking *through cPanel* until the period has elapsed. This would minimise the opportunity for such abuse. The checking of such a period would need to be implemented across the DNS trust in order to be useful.
