I noticed the exact opposite of you - I don't really see a ton of ways townies die quicker than the normal pace. What makes me nervous is I saw a ton of ways for mafia to keep their players from being lynched and get townies lynched instead.
From the quote, my thought was we lynch the last laugh, get his alignment, and then lynch the next person to get him back if he was townie - basically confirming a townie or mafia. Upon rereading, that doesn't work as we do not get the alignment of the person killed.
And really, spammer scares you the most? It can be pretty easily combated, and is relatively obvious. The one that scares me the most is definitely the kingmaker, and by far the largest reason that I want claims the day after - if we don't, mafia can redirect a lynch anytime they receive the kingmaker (until they have 1 person), as well as any time a townie accidentally gives them the role.
