If personhood is an interface then it naturally lends itself to hacking. And of course there are methods (power plays, social tricks) that technically violate the rules (implied threats of violence, walking out of a meeting, whole pickup routines) but, when successful, don't result in user experiencing any loss of personhood, quite the opposite.

There are whole life strategies which are based around hacking the interface. Technically, we sometimes call people who choose them psychopaths and therefore less than persons, but realistically they often go undetected.
