I'm treating the infractions for using an ability like a global watcher role. Those people were seen using an action and someone died. In any other game, logic would dictate that one of them likely did the kill.
If we followed Dupti's suggestion and all agreed not to do a night action, all scum would have to do is not kill that night and no NK would happen and nothing is gained other than we have to rely on talking to determine who to kick out of the game each day. It's harder for scum to some extent because it'll take longer to whittle down town to get to a majority vote, but also harder on town as we have proven that scum can slide under the radar on days fairly easily if there's no cop night investigation to scare them into being exposed.
Plus if listo is being truthful and no one targets him tonight he will die and then we will observe a death without a night action. If he is town we have aided scum in narrowing down the field for them. I'm not sold that he is being truthful since he's alive and no one said they targeted him last night but I only have a loose working theory on how that would be possible at this point.
