Peaceful and Man — Happy, Vervolka, Deriel (not certain, but likely)
Mafia players — Pandora, Plesen
I won't assign Xostor to any group for anything. I'll note that all his posts literally reek of peacefulness; there is nothing to nitpick. However, I would be a fool if I didn't know how strong and cunning a player he is,
Therefore, I'm not ruling him out.
I don't think the maniac specifically singles out mafia players for himself, so there may be more victims among the peaceful population at night. Something needs to be done about this.
Now I'll explain for those who aren't aware (I hope I'm right?).
Xostor leaves his red vote against me not because he wants to execute me (he's no fool, executing over one not-so-suspicious post), but in order to "spur" me, so that I give him an answer to the question "Why against Lizarde?" But Pandora, who joins in, doesn't understand the game mechanics and is seriously trying to execute me. If Deriel hadn't thrown a couple of lightnings, and Vervolka and Gur hadn't given me blue votes, I would be the one hanging right now.
Therefore, I'm noting Pandora as mafia.
And I'll keep an eye on TaCo, by the way...
P.S. Ney, for your notes: you can't leave without leaving a vote (unless you're mafia, of course :D )
It will be no trouble for the mafia players to figure out who has -2.

Ah, I also have a feeling that Koteyko is peaceful. Although I haven't reached that page yet.
