In response to Swan's Joseph case, I have a bunch of my own reasons for thinking he's quite scummy.
First, though, just so as not to confuse newbies, please note that the thing Swan does by saying "Joseph!EFHW" to indicate a Joseph-EFHW scumteam is not standard notation and will wind up players like silverspawn or me :-P The much more standard thing is to use the "!" notation to talk about a version of a player, like town!Space or SK!Joseph, where the property goes before the exclamation mark, and the player's name goes after.
Anyway, I have some wagon analysis reasons for thinking that scum!Joseph is a strong possibility, but nothing very damning yet. Most recently, for a lot of early D2, I had e, Joseph and Robz on my tail, and the wagon stalled. Other people had expressed interest yesterday, and I think scum would have pushed my wagon more had there not already been one scum in the mix. I'm far more inclined to think it's Joseph than e, but I would be very surprised if they're both town.
In early D1, faust and I were voting for Joseph for a long while without the wagon taking off. I think Joseph is someone who's quite easy to push at when he's town, so if we have scum!Joseph then I think his buddies might have been aware of this and worried about bussing because it risked pushing him to far. Conversely, hypercube and Fang are the two that made his later D1 wagon take, so if they flip as scum then I'd think it's good evidence for town!Joseph. It's an interesting possible correlation, but not one I can use for very useful conclusions right now.
I've just also realised that hypercube used to be chairs.. I'm afraid my rolling-vote-count script just asserts that "chairs" is a variant spelling/nickname of "hypercube" for this game, so I only see hypercube's name there now. Apologies if I do more wagon-gazing and get the subbed-in/subbed-out names mixed up.
