I'm questioning the conclusion BigTerp got in post
108.
Confusion is a tool that can be used to town's benefit. While mafia may use confusion to manipulate town to some extent, mafia doesn't like too much chaos. The more confusing the thread gets, the more room there is for scum to slip as they aren't prepared for the confusion. The mafia relies that things follow their agenda and if there is no structure, it's hard for them to fit in.
Oftentimes a quiet, structured or stagnant game means that mafia is in control of the thread. If mafia were close to being caught, they'd try to use chaos and confusion to get out of it. Obviously, if nothing confusing or actionable is happening, mafia is perfectly content with their position in the game and that's a bad sign for town.
I don't think joking or meta reads have helped mafia, really. If anything, they've helped town. Joke posts are often relaxed and authentic, something which can be harder for scum to fake. Talking about a previous games can help contextualize, to those of us who haven't played or spectated those games, about who has meta reads on each other or who has radically changed their playstyle since their last game (possibly indicating an alignment shift).
