So I decided to look over the posts of the three confirmed baddies to hopefully turn up something that might help us find their teammate.
Floyd
Worth noting that Floyd voted Prog. Perhaps he was the baddie with info. His first on topic post was to demand an explanation for Banana's vote on Bugla (later replaced by Draconus). Later voted for Bugla himself for sketchy reasons so...

Would certainly be weird for all three irl friends to all be randomly sorted into the same team. Paid respects to Luke and voted for JC but other than scattered individual mentions of a few people, Bugla is the only other player Floyd said much about so I don't think there's much to be gained from reading his posts.
Luke
Listed two people as good: Floyd and Sorsha. Didn't have an explanation for either read. Not much else to see, I think it's equally possible that he listed two of his own teammates as it is for him to have mentioned Sorsha as well as Floyd in order to make her look bad should Luke be lynched.
Juliets
Something interesting I did notice is that two of three confirmed baddies followed the Sig case on day 2. Floyd seemingly missed the vote entirely. Perhaps it could be worth revisiting Sig voters, perhaps they all jumped on board as it was an easy target. We know that at least three of the voters that day were not civ-friendly folks (with nutella the dangerous bad indy also getting in on it).
Early on JC also spent some time trying to draw Floyd into conversation - probably trying to be a helpful teammate, knowing her. JC also said she had no suspicion of Sorsha, so that makes two baddies saying that. Worth keeping in mind? She also named Bass as a neutral read.
Overall this stopped being useful pretty quickly I think, but I decided to see it through. The only thing I've really noticed is the Sorsha point, but it could be completely meaningless. I'm also going to revisit a couple of old suspicions that have fallen away in more recent days. The suspicion list I posted early on now only has two or three living people left from it, so that shouldn't take long.
