It's this one, right? I must have missed it.
So basically, you're saying that players will want to keep a good AGer alive, so they will vouch for them, right? How does this actually make the person in question innocent? If vouches depended solely on how good you are as an AG player, then wouldn't the top players always survive since everyone vouches for them? Looking at it from a logical view, the only people who would not vouch for my innocence are those who either are assassins and want to direct the lynch away, or people who are also being voted for and want more suspicion to fall on me. Then there are those who are not sure of my alliegance either.
But if you want vouches, how do you suppose I'm going to get them? Do I just post here saying, "Can anyone vouch for me?"
