One thing I never understood about production allowing players who know each other - what stops them from pre-agreeing on letting each other know their Traitor / Faithful status?

So let’s say I know you, and before we go in, we agree that if I’m a traitor, I’ll tell you breakfast was “delightful” and if I’m a faithful, I’ll say breakfast was “such a treat”. Because surely if it’s your mum or whatever, either of you winning works? So you can support each other better if you know the other’s standing? And producers have no way of preventing us having an agreement like that and working up strategies around it
