Skimming through the roles, I see a potential flaw: Scum are not informed of their teammates in their PMs. This gives the possibility of “ignorant” Scum who don’t know who their teammates are (since the mods don’t force someone to read the secret forums). Scum who can’t coordinate or even know who’s on their team are much harder for us to find.
Perhaps the game was balanced with this in mind. In any case, we should not expect Scum to know who’s on their own team.
