Yes, but if the mafia are good players they won't get caught into far into the game. If they wait for say, 3 days, the mafia may feel safe enough to start taking shots with impunity
That's still absolutely fantastic. I don't think you understand how much of an information advantage extra lynches are for town.
Though why are you assuming that there's some "super-team" of mafia running around?
I heard they gave the mafia members steroid's to make them a super-team...
