mrkgnao: Let's imagine for a moment that CSPVG is scum. He visits on post #559, sees that adaliabooks is for all practical purposes lynched and decides to hammer.
He also notices that adalia's claimed ship model is identical to his. The only models he knows about are his, adalia's, and the one in the OP. He has no way of knowing what the logic of the models is. For all he knows the Iniurfas Mark IV might be unique to scum. By revealing his model he might be revealing his identity. I don't think that a reasonable scum would at that point rush to reveal his model to the town. A reasonable scum would sit tight, hope that whoever scans for ship models skips him, or that the logic of the models is eventually revealed to be more sophisticated that Iniurfas Mark IV = scum.
I would like to add a thought to this.
Assume for this argument he is scum, as you say. At the time CSPVG hammers, he actually really only knows two ship models, his own and Telika's. He knows what adalia has claimed, but unless he received his buddies ship models via initial PM, he has no way of knowing if this is true or simply a part of adalia's gambit. So, he sees adalia claim Mark IV. If he is the same model, I can see claiming the same for exactly the reasons you point out are townie. It worked, didn't it? You score him as more likely town because he revealed information that the rest of us cannot confirm or verify, and may or may not have any consequential meaning.
WIFOMy?
Yes, but I point it out to show that this reveal is not exclusively town-leaning for me. Just like trent's nighttime PM, a player "revealing" information that is impossible to corroborate and yields no actual facts, to me, is distraction and inherently unproductive. I don't award town points for such.
This doesn't mean that I put CSPVG firmly into the scum columng, but it someone wants to convince me he's town, the ship model reveal is not going to do it.
