The "no lynch is ok because it avoids the town being lynched which is mathematically more likely than lynching scum" needs to S T O P. the basic mechanics of mafia games is such that town has LOST if the game is ever more non town than town, right? If it is say 6 town and 7 scum -- 'Hey, we can finally have better than 50/50 to lynch scum !' 'oh wait now we don't have enough votes to lynch scum!'
Seriously, no lynching is ridiculous there. No lynch mechanic is for specific purposes such as mylo when no solid leads remain to ensure another night and day phase to figure the game out.
