It’s either a type of insurance (#318) or security against liability for damages (#317).
How so? I can’t say it’s true of any evil player, but for a person like Zenon who prides herself on her evil ability and hasn’t randed Mafia since a disappointing showing in Starcraft (as far as I know), I would expect receiving a red rolecard would result in her making a point to appear in the thread at some point.
By this point I think v!Zenon would’ve tried to jump in either way though, so she’s probably just busy.
