I think Maxford is an uninformative choice, and not as likely to be scum as either faust or Galz.
For one thing, flipping him gives us next to no wagon PoE from D1. He was the very last player to place a vote, and then it was on me, which doesn't even tell the rest of you anything. Then he unvotes! No decent wagon interaction at all. He joins the Shraeye wagon late, and is on-wagon for the lynch in 6th place.. it could look scummy, but it could also just look like a hesitant newbie, so it's all a bit null. Most of the rest of the people there (besides faust and Joseph, or Eevee right at the very end) have already flipped. So let's say there's zero info to be gained by knowing Maxford's alignment over D1.
D2 he joins Eevee pretty early on faust. And then he sits there until the end of the day, and doesn't participate in the MiX lynch. Now, granted that's a tad different from his D1 behaviour, but is it different because he's been coached over N1 in the scum QT, or just different because he'd been around long enough to have developed a read?
D3 he just didn't vote.
In summary, yes, he could be scum, but I don't think he's our most likely chance of finding scum today, and I do think he's a contender for the title of worst possible person to flip in terms of possible scum-hunting boosts for town.
