Well let's take a look at the players, specifically those who have played before:
1)Jordon987 - played 2x, both times innocent villager
2)Denisero - played 1x, was mafiosa
3)Darknoon - played 2x, 1 time mafiosa, 1 time villager
4)Gem - played 1 times, seer killed by mafia first round
5)Zortar - unknown
6)Anhlong1122 - played 2x, villager both times
7)George Hurst - not sure if george played both times or not. mafiosa 1x
8)David Schofield - unknown
9)Dazzy - unknown
10)Kurtis111 - unknown
11)SauceySauce - unknown
12)Divest - played 1 time, innocent villager
Going with statistical probabilities, anyone that wasn't an innocent villager before, particularly in the last game, most likely is a villager now. We have 5 players that haven't played before so we have no statistics to look at for them. This leaves the following 7 players that have either been innocent each game or is an unknown factor:
Jordon987
Divest
SauceySauce
Dazzy
David Schofield
Anhlong
Zortar
I'll have to think on this some more but my choice will be from that list.
(I wonder if I just signed my death warrant)
