As for Malevolent, I don't buy the whole not reading of PMs. In a game with proper stories and character backgrounds, that's one piece of information one cannot pass by.
Right now, I have two theories on how the game might work:
1. Sathoris is playing the role of the Sphere and is randomly choosing people each night to become mafia.
2. All players received, randomly, a name from the list of 4 and then a number of them received the anti town status. The lack of a kill on night one might have been the result of a doctor save (the comment about the meds I made yesterday) or some other reason which could include recruitment, since it has been brought up several times by now.
