Voting.

Voting is ultra-important. It cannot be overstated how important it is to do so. Voting records give us something to work with. See my reasoning for voting Refia? I cannot know if Refia is scum, but her liquid vote shows some kind of weird erratic behavior. Maybe her mob mates were telling her to change an impulsive vote? Maybe she does not want to be seen piled up on a potential lynch? She jumped on Penelo after leaving Blank (the first bandwagon), left Penelo (because it was so absurd?) to start Wakka's lynch, and then left that for Quistis when Wakka got a few votes.

You can hang yourself with a shoddy voting record, yes and that sucks if you are town. Think of the other townies though how are they supposed to trust you if you cannot even try to grasp for a link in the chain? But think of how mafia got to vote. They have to build up a lynch on a town without it being clear they incited it and they too have records that will show how sly they've been trying to be. Everything that is hard for town is doubly hard for mafia.
