I thought I’d done this earlier but I’ve just realised I hadn’t:
vote Spawn
Also, gods help me, I’ve just run a quick search on “Perfect Information Syndrome” mainly in the interests of cutting short yet another sach vs story dispute. I certainly don’t intend to track down every single PIS vote, but the first one I looked at was from Lost, when Zeriel was picked up on PIS and turned out to be scum (and the person who picked it up was town). So it can be a legitimate means of finding scum, as well as a scum tactic for placing a vote.
On a more general note, I’m pretty sure that the reason we have an acronym for PIS is because it’s a behaviour that was observed in the wild and classified, not an esoteric theory that sprang into being with no empirical evidence. That it *may *now have evolved into a tool used more by scum than town is just further proof of how splendid and complex a game Mafia is.
