As for today, there's a player in the town who definitely should know the Mafia's nickname (based on the game mechanics). Logically, he should confidently push for his execution today, within the rules, of course. Out of all the players, only three (with some reservations) did this, and they all voted for Krabby. Therefore, the only other possibility is that someone from the town is deliberately helping the Mafia, and I don't see any other explanations.
