Laundry feels town to me. I see him asking good questions (ie zen reasoning, ryker not doing enough work, putting out his summary), explaining himself, and not backing down when called out on fakeness. I would say that he should have waited on Gheb to explain though as it'd help me read Gheb further. Laundry is putting in the most work here I can see. I think he believes his argument on Soup, but think he's wrong.
Maven is still suspicious to me. Here are his original scumpicks: "Gheb, Soup, Ranmaru." Now Maven pushes Laundry. His reasoning to even have Gheb as a scumpick is very weak, and I find it as posturing to seem like he has something. (Which he reverses) He also states he hasn't seen anything from Soup that seems pro-scum yet had him as a scumpick. Now he uses that against Laundry, and I find this inconsistent. I would understand his feelings if he stated this in that very post, because Soup was coming off the same way as he did after that page. (Lazy, reactive) Yet he hadn't. I am also not convinced by his reasoning that Laundry's post about Orbo is fake, and I find that (Maven stating that's really fake) to be the most malicious thing I've seen from anyone. My vote stays on him.
Gheb is null. I don't see anything convincing from Gheb's argument. Nothing I see from Laundry is suspicious and Gheb is not looking at the whole picture. I don't see how bad = scum, and I am not convinced by his point of blowing the complaint out of proportion. (Which seemed to fear monger people into switching, instead of using actual reasoning) I don't see how being a leading proponent against ST means anything, since it's a weak reason to consider anyone suspicious. I'm null on Gheb, and I don't get anything from his reads in general. They aren't really fleshed out, for example his ryu read, his maven read, his (me) read.
In general, I get the feeling Soup is being lazy, and reactive. I can't really pin it as townie or scummy, and I'd need more of a push from him somewhere (besides Laundry, because I did not even remember it until recently) to really garner his intentions. I really like some of his explanations and I can agree with them. I get a null-townie read from him. As stated above, I would think a scumSoup would be working harder to seem town than when he'd be town.
So I'd lean on Maven being the most likely scum here out of the three. I don't think think it's good to try to determine scum being on the wagon or not since it's only 3/5 and I wouldn't really look at anything until after a flip. Plus there are people who have yet to vote (like Ryu/Orbo).
