I would put my scum reads in to two pools. The first is DCPat and Turmoil, both of whose voting records I've found to be suspicious. I felt a little better about DCPat after D2 and a little better about Turmoil now, but both have been giving me the worst feeling. That said, though, I'm not sure if I could see them as scum-mates - I think it's one or the other, and right now I'd lean more towards DCPat.
The other pool would be those who seem less overtly scummy to me - in that group, I'd put Nin, AB, Melon and Z-Beat as things are. They've all been on my radar for one reason or another, but not as strongly as DCPat and Turmoil. They would be the next group that I would be looking amongst.
Zeke, for what it's worth, seems like town stuck in a tunnel to me. While I'm now more dubious of Melon's voting history myself, I don't think Zeke's obsession with lynching her - and that's how I see it = is especially helpful, considering that he seems determined to take down anyone that he perceives as getting in his way. (That's the only explanation that I can think of for his scum read on myself.) The only serious possibility that I can think of regarding him as scum would be if he and Melon were team-mates trying to put distance between themselves, as I've mentioned before.
Right now, I think I'm going to put my money where my mouth is and place a vote on DCPat.
VOTE: DCPat
