The way I see it snoop is OP on 2 fronts. It’s schrodingers’ strong (IE the sort of ability that’s strong enough to fuck someone up, without the class even being in the game.
Here’s 2 scenerios.
MM1. Keeps a solid princess log in his journal, and a butler log in his private notes. Day 4 he’s called out by a drunk as occupy immune. MM goes to his private notes pulls out his butler logs, assasain even backs his claim, BD seems to be buying it until “Noble: N2. snoop MM - Princess logs”
MM2, keeps very consistant logs all throughout the game, he realizes that if he’s been snooped he needs to stick to the claim he’s made, This game he’s going with a butler log. King whispers MM2. “a princess tells me you are also investigative, what’s your class”. MM tries to flip that around and say the princess is lying because he’s butler… he gets voted up, learns later that there never was a noble in that game. Had he just claimed an investigative class, he’d have been just fine.
The very consistant strategy of lying as evil in social deduction games is “Keep your claim liquid until you are forced claim, once forced hold to that claim against everything unless you have a damn good reason to explain a change of claims”. Noble puts a wrench on that in the sense that you literally don’t know if you’ve claimed or not.
