I read a bunch of snippets of old Thor games trying to figure him out. Based on the section you read, he was a scum read of mine at that time too. But I've since moved him to town. I'm no expert on him though, and I hate to say too much since I haven't played with him outside this game, just read his ISOs in some old games.
That said, here's what I think I've figured out about him.
He seems to be abbrasive like that as town or scum, especially when he think people aren't paying attention to the game. This avoiding-giving-clear-reasons-for-votes thing annoys me, but again, he seems to do it in town and scum games. I get the impression he'd have been willing to outright policy-lynch wgeurts even if there wasn't any scummy timing to his hammer. I'm disinclined to read him as scum from that. (Thor, correct me if I'm misrepresenting you here.)
As for why I have him as a town read:
1. He seems frustrated with the game in a way that I suspect is townish of him, specifically he seems annoyed with the lack of effort on behalf of town players. I sort of think he'd try to guilt us a bit less or a bit differently if he was scum. I developed this impression when I got into the kerfuffle with him about his accusing me of not reading.
2. I know this is a minor thing, but scum have daychat in this setup. As I said to Acryon, I think if Thor were scum, he wouldn't let his buddies slack the way they've been slacking. I get the impression that everyone has been kind of half-assed this game. We've had so many replacements. I could hypothetically see a Thor/DXCVIguy scumteam, and early on I had thoughts of a Thor/Droog scumteam, but I just can't see him being scum with most of the players in this game.
3. When he started taking heat for making the game harder to read, it looks to me like he legitimately started trying not to, particularly sometime after I replaced in. He was huffy about it, and didn't say much about it, but he seemed to fade back a bit like asked. I think he could have been more disruptive while seeming townish and gotten away with it.
4. Process of elimination: Of the other players remaining, I find 4-5 of them scummier than Thor (I've been reevaluating your slot recently, and I think I'm back to the same sort of weak-but-going-with-it town read as I have on Thor for the moment). We know there are 2/8 scum, not 5/8.
That said, I think meta arguments are probably not so great here; something I gathered looking into him is that Thor is hard to read even to people who play with him a lot. So I think that if he
is
scum, the best chance to catch him is to catch his partner first. Without something much stronger, I'm not intersted in lynching Thor without lynching his scumbuddy first (barring some hypothetical endgame scenario.)
