I didn't think Libk's initial suspicion against Moe and the others who made the read list was too bad, mostly because I can imagine a townie having legitimate paranoia about scum coordinating. And him then claiming that his finger of suspicion didn't actually indicate suspicion was weird, although he might have just misunderstood its usage.
But his OMGUS and subsequent tunneling of Moe (even up to now and without much other scumhunting) doesn't look great, especially since it's not based on much at all: he said Moe's exasperated response made him seem "flustered," which seems pretty weak and contrived. He's offered more reasoning now, but most of it comes off more as venting frustration than explaining why his behavior is scummy.
I think scum will often vote themselves with the idea that a seeming disregard for their life will make them seem town, or at least sympathetic or victimized somehow, but it usually does the opposite, and that's because there's just never any good reason to vote for yourself as town. I've seen scenarios when town players get genuinely upset and do it out of anger or spite, but at that point they're not actually doing it for any game-related reason, and that's not what's happening here. I agree that it's probably a scum tell.
And of course, Libk gets absolutely no town points for being (iirc) the 6th vote on Kreaal's wagon, especially given that he was initially town reading Kreaal and barely mentioned him for the rest of the game. He said he wasn't down for a second no lynch to justify his vote, but there was really no chance of that anyway. This is probably what motivates me more than anything right now.
I'll very likely end up placing my vote on Libk before the day ends, as while I doubt we'd hammer, I'd rather not risk it. If he flips town, then I might have to reevaluate my town read on Moe.
