AKPERSON is a term I use to abstract from every agent accessing my domains. It is also the SKU or product/service code used to designate various levels of paid services vended in-app as payment in various applications.
Third class AKPERSONs are either anonymous humans or machine agents.
Second class AKPERSONs are subscribers that pay a reduced fee, below the standard offered price for a thing or who are not currently subscribed but may have been in the past.
First class AKPERSONs have a current account for service at the unsubsidized price including any discount offers.
