This is something that came to light behind the scenes:
JDodge had, initially not read his role PM. He told the mod this, and then the mod forced his role upon JDodge. This led to JDodge being angry and threw a massive fit in scumchat yesterday with regards to Oman's behaviour.
Now, the only reason I can see for not reading role PM is to not know you are scum. That is the biggest advantage of playing without knowing your role. Upon knowing his role, JDodge became angry. This points to the fact that JDodge is scum, because had JDodge been told that he was town, he would not have any reason to become angry.
