Why
are most liars scum?" - this is a result of the LAL mechanism.Say I'm in a C9 newbie, I'm vanilla, and I'm being bandwagoned Day 1. What do I claim? In a LAL universe, I'd almost certainly claim vanilla, and continue to try to talk my way out of it. In a non-LAL universe, I might choose a different action - fake-claiming gives me a 50% chance of no counterclaim, so improves the towns' odds, if people believe me. If they don't, I can explain why it was a legitimate pro-town action for a pro-town player, and then what?
The LAL is to discourage such behaviour which otherwise, I think, could easily slip into being standard practise (with WIFOM variations, naturally).
