Message every who isn't married with "Do you like merits?" Worked for me. Doesn't even matter if they are inactive because you still get the merits. As for the PI...
Received a similar message from that Lisa, too, when I started playing Torn. Didn't know what he/she wanted from me. It was the same weird content about that Lipstick_Boy.
Edited: And I haven't placed any Personals at all.
I got this same message day 1 of playing lol no idea what the story Is behind this one but I blocked the person and the lipstick boy person they were speaking of, and moved on with my life.
