Well going back through, Djinn was fairly inactive, yet she was town. Though she could have been trying to hide the same cliche way scum does to try and protect her power roll. The only one who really openly opposed was Gonzo, though I believe
his post to be an authentic scum hunt. Not entirely certain though... IGMEOY, Gonzo, if for nothing but I don't have much else right now.
Go_Dark_Link was just as inactive as Djinn. As were a lot of people; more people then there are scum. This tells us that not all the inactives are scum, but potentially; keeping my eye on them too, but it's not definitive. As far as his posts, I cannot detect any real scumtell, so I have to assume the person(s) who targeted him did so randomly and we got lucky because of it.
Finally, remember that Elfen looked really scummy before he got replaced and the votes reset. Though this could have been for a number of reasons, Zenox has been a ghost, only appearing when necessary and not really saying anything significant. That could be a scumtell in itself, though for different reasons. I want to see more of him before making any accusations, though IGMEOY too, Zenox.
