I think it'd be better to hold off on Onion for now... kind of on the fence because I think it's more likely that an AFK player is mafia.
If you had messaged me and claimed to be mafia, I would have told you I was mafia despite being a civilian. So the fact that Onion took a different approach makes me wonder...
And that's a good point, UTA. I didn't know ties could randomly choose mafia, so it would be better for the two TSF mafia members to vote for the same person.
So being AFK doesn't mean quite as much as I thought. Still not convinced on Onion though.
