You're using lynches to get information as town, correct? What kind of information are you hoping to gain from an N0 vig? If someone is about to get lynched, they can make claims about the information they gathered or the suspicions they have and have town accept them as not a mafia ploy when that person dies and flips town. As long as a GN dies tonight or day 1, I still have faith in the potential for a lot of information to be gathered by town without relying on killing people. I might even favor no lynch day 1 if someone dies as Golden Nymph tonight, unless someone has specific information that leads them to believe someone is mafia.
The crucial point is that not lynching people does not necessarily cause the game to go stale with no new info for town on whom the mafia are in this game, while town is being picked off one by one. This is a crucial point on why no lynch is generally bad.
