What if the citizens secretly send each other a screenshot of the initial PM by Kate? The one that said whether we're citizens or gangsters. That doesn't take care of the recruit but we'll have the two other G's for sure because they won't be able to send anything.
I would've sent em to Kyle since he's the confirmed BG. As in everyone would send them to Kyle, and whoever didn't or had it photoshoped, would be the G.
