StK. Why would town claim mafia. twice. in one post?
they won't. Nor will they use sarcasm when criticized, or even (in case of the theory) ignore it.
unvote vote mindgamer
Further, scum and town differ not in the mistakes they make, they differ in the motives they have. Town wants to find scum, they try to make the game understandable, but on the other hand, not predictable for scum. And they want the truth.
Scum wants to stay alive, wants the game to be orderly, and from this (mostly the first) follows that scum usually have the motive to be not noticed (WIFOM, but with a larger percentage to the scum hiding)
All the tells you have in the wiki come down to those motives becoming visible, but they only work in sometimes. Omgus, for example, is a inaccurate tell since townies who are "unfairly" under attack have the idea their accuser must be scum. Scum misuse it to get their attacker under pressure, but this isn't happening very often, so that tell basically doesn't work.
Bandwagonning, the adding of a vote to a bandwagon while you have given no explanation other then that you want to lynch that guy is a more effective tell, since this could show the motive of scum that they want to stay alive (and to direct the lynch on a towny), starting a wagon, on the other hand, is more risky for scum.
etc etc.
Surrender, imagine and of course wear something nice.
