I don't think someone said he is scumreading you at 100%.
You are just the player who is the most scummiest at the moment .
That's quite sad/bad if we are scumreading you for an important moment when you were not in a right mind/drunk/whatever but that is how we are playing mafia. We can only read what you say/do and not how you say it. And by 'how', I mean your body language.
Obviously we should know if you are drunk or not paying attention if we were all face to face
But yup, at the moment, if someone have to be lynched, it's you.
