Pretty sure those would be better at social engineering than the web dev personality… except that you have to build in a betrayer layer into the personality, so it's running that stuff but also serving a hidden agenda.
You'd be basically trying to build an AI spy, a betrayer that's engaging with actual people but has an agenda (for instance, 'everybody I befriend needs to eventually be signed up to sell Amway') and humans do have experience with this sort of thing. The difference is scale: there'll be a LOT of models out there interacting with people and trying to be acknowledged as people… or as innocuous models that don't have an hidden agenda.
