I quite honestly don't care too much if I am in your group, what I care is when you are wrongly analyzing why the spy is, and that assessment will ruin the game. If you want to keep me out of every other mission, then please do so. But dont assume that I am the spy, b/c I am not. I approved right when I finished lunch at a pizzeria, and arrived back at my vet hospital 5 minutes later to have a DOA dog being rushed in. So no, wasn't really in a position to check my phone from then onwards.
If I was a spy, I would have voted for success, its a stupid move to vote for failure on mission 1.
