@Human; It's not a random suspicion. You were giving up some pretty big scum tells. Trying too hard to seem town is a scumtell, as is active lurking.
You soft claimed a power role. Soft claiming means you imply that you have something, but don't outright say what it is or admit it. In your case, it was extremely vague, but from what you said it seems like you're implying that you have some kind of powerful active night ability since you compared it to cop and doc and you said you'd seem inactive when you used it.I don't want to use my power role to get a higher ranking that would make me be targeted by the mafia of possibly being the cop or doc.
