I would've, too. It makes sense: they were the most dangerous player that didn't have any real suspicion on them.
If you have a Mat/TUN team then based on D1 voting you probably have a Mat/TUN/Szeth team, which you don't.

In other news, I feel like I'm coming down with a cold :<
That might actually increase my activity
Edit: @ookla the POKE VOTE, could you elaborate on how you got to that set of people?
