As it stands, a group of residents can watch the airlock, grab a scanner, and pick out a name on the log. It usually turns out to be a Personoid. I believe there could be a rare item that Personoids can find that is able to fake a resident scan once, this would be extremely useful in keeping an act alive, gaining trust, and betraying everybody. This would be counteracted by the logs of course. This could be added into a gadget shop that the personoids have access to, like the terrorist do in Trouble in Terrorist Town.
