Taking out the four masons (unless there's a fifth claimed and I missed them):
2) Simenon - mason
6) Ether (replacing Honary Hitchhiker) - mason
18) Niv - mason
21) Bookitty (replacing booboodafool, replacing Celtic18) - mason
Leaves me with:
1) Korejora (replacing Aimee)
5) JDodge (replacing ckillor)
7) Sir Tornado
11) ZONEACE
15) Setael II (replacing Flare)
17) Elmo (replacing Beastly)
Of which I'd say 1-2 are mafia and 1 is SK/vig if we have a mafia-mason. If we have an SK-mason, I'd say probably 2-3 of those 6 are mafia.
Aimee/Korejora: Was suspicious of Zorg early in the game, and I don't think the Korejora/BM argument was staged. I don't see BM getting into huge attacks and arguments with his scumbuddy. Conclusion: probably protown, or at least not mafia.
ckillor/JDodge: Has almost no contribution throughout the entire game. JDodge has 53 posts, and almost none of them contain original reasoning, or any reasoning at all. Conclusion: Leaning scummy, needs to actually participate. Lurking in itself is not necessarily a scumtell, but this seems more like active lurking.
Sir Tornado: I don't really see much that stuck out to me on a reread, and he's pretty active. The only thing that I noticed is that he's been discouraging any theory that involves a scum mason that can communicate with the mafia, but that's not really scummy since we don't know how it's set up. He does have some reasoning behind it, so it'd only be interesting if we had a way of finding out how the game is set up. Conclusion: protown
ZONEACE: He's playing mostly as himself, but that doesn't clear him as town, it's just not evidence of him being scum. In fact, skimming his posts, I find him lacking in contribution much like JDodge. He's done a lot of voting and attacking of people, but he hasn't really presented cases for his suspicions. Conclusion: Leaning scummy
Setael II/Flare: Flare was pretty scummy, but Setael redeemed the role somewhat when he replaced. I've liked a lot of his logic so far, so he's in the middle atm. Conclusion: Neutral
Elmo/Beastly: Beastly seemed pretty logical, and I like Elmo's posts so far, but Elmo needs to be more active. He only has 7 posts since replacing 2 months ago. Conclusion: Neutral leaning protown.
My suspicion list (scummiest first):
JDodge
ZONEACE
Setael II
Korejora
Elmo
Sir Tornado
