It's based on speculation about the role cards we received which are different from the role cards listed in the setup thread linked in the first post of the game. I didn't and don't want to talk about this until after the game because (1) it's cheap if I can confirm myself as town because of something related to host error and not based on in-game interactions and (2) obviously not an indicator of scum or town (as I keep saying) because Hybrid used the post relating to what I said about my role card "confirmed me as town" and yet he flipped scum.
I don't want to talk about it more than this but I'm answering since you all are super hung up on it.
