Just to prove my point, I noted Ghost's meta is to scum claim as town. If he was trying to level us with an early town claim as either alignment, it would it no way invalidate that his past meta was fake claiming scum as town. At all times, you should always take into account that a person could be switching things up/leveling you/trolling/ whatever. None of that matters because what you are really trying to use is how a person thinks about the game and then using that knowledge to read them. Meta reading isn't actually saying a person does A as Town and B as scum "all the time"; it's understanding why they usually choose those choices in the sample you have seen and then reading their alignment to the best of your ability using all of the above knowledge.
