This is a doosy, pay attention.
Quote from Doodle77, page 6
NudeRaider is German, and his avatar has shiny glasses, so thats a pretty strong clue pointing towards him. But note that the german with the sunglasses isn't mafia in the text.
This is the first, and one of the very few, viable clue interpretations of the game (I think).
Please note that only four posts from here Darkling (just beginning his aggressiveness) says:
Quote from Darkling, four posts later
What if obnoxious is maybe an adjective, not just describing the glasses? Doodle77 and Greo each have obnoxious critters for avatars.
A rather junk accusation (why is the goopy pokemon obnoxious anyway?), but the beginning of a bandwagon. DM also dropped a hint at the sevens, but neither of them drew it to Doodle77's name. The connection was made by Hailfire (page 6).
HOWEVER, both Darkling AND Darkmarine immediately agreed, but neither voted.
Inferno was the first to vote (page 7), but Darkling and Darkmarine followed, once again immediately.
From there, I have this theory:
Doodle77 makes good accusation (this would probably mean NudeRaider is a mafia).
Darkling drops a hint on Doodle77 and Greo from obnoxious clue (bad, baseless accusation).
Dark Marine pulls in bringing up "7" and "username," but does not connect with Doodle77 (you'd have to be paying no attention not to notice it, both DL and DM are setting it up here).
More lousy discussion continues, but eventually HailFire points out the connection between Doodle77 and 7 (the two practically spelled it out already).
VERY NEXT TWO POSTS: Darkling and Darkmarine immediately agree, but only subtly, and without voting.
As discussion continues, Inferno casts the first vote.
VERY NEXT POST: Darkmarine votes for Doodle77.
TWO POSTS LATER: Darkling votes for Doodle77.
Seem suspicious? My theory, thus, is that Darkling and Darkmarine, and probably NudeRaider, are mafia. They set up accusations and connections, but remained subtly non-aggressive.
