A policy lynch I agree with is "Lynch all liars" because townies have no reason to lie.
VI (Village Idiot) behaviour is something that I have, as yet, not really been able to distinguish from out-of-control scum behaviour. I think it's certainly
easier
to policy lynch people for being anti-town, and there are benefits:
(a.1.) Anti-town by definition harms town in a number of different ways
(b.1.) Arguing over anti-town behaviour can distract town from real scumhunting, and so getting rid of it can be a real help
(c.1.) Lynching a VI and analysing their wagon can be pretty helpful in nailing scum
But I don't think it's
always
the best course of action to follow from a "policy lynch" standpoint since:
(a.2.) If the anti-town behaviour comes from a townie, policy lynching gives scum an easy vote to ride on
(b.2.) If there are multiple anti-town players, all of whom are town, you can rinse through mislynches very quickly
(c.2.) Sometimes it's possible to read legitimate VI reasons behind anti-town behaviour (this brings out bucketloads of WIFOM, which is where my difficulty in distinguishing between scum and VI arises)
I have played with Shotty once before, and he was sometimes anti-town, and occasionally pro-town (although, in that game, I was scum, and so I knew that he
was
a VI). I think we ought to give him a chance in this game to see how he plays before deciding whether to policy lynch him from the get-go. If he becomes harmful for town, then I'd definitely get on board with his lynch - but I'd vote for anyone who I think is out to harm the town. Taking play on a case-by-case basis forces people to submit reasons for their votes (beyond "Policy") which helps with (c.1.) immensely.

You shouldn't lynch someone if you're "certain" they are town (I understand "certain" as having factual evidence, from a cop report, for example), and I don't think you should really vote for someone if you're "pretty sure" that they're town (unless their flip has some benefits beyond getting them out of the game; if you need me to expand on that then I will, but it probably isn't pertinent right now). But the fact of the matter is that if they're acting "anti-town or idiotic," it's very unlikely that you'll ever be "pretty sure" that they're town.
