Spent hours thinking about your question and debating what is and isn't scummy in my mind, and I'm scumreading Best.Korea. There's just so many sus things B.K has said that I can't justify all of them.
1. The whole "Idk what to do" thing in Post #6, only to be followed up by a lot of comments that look like he's pretty sure of himself (a new example of this contradiction is found every time they post).
2. The immediate town read of you in Post #7 based on your research. I'm not saying that announcing research is inherently scummy, but it's not inherently towny, either. It's not something that we can use to evaluate affiliation. At first, I said it was only slightly scummy because it could just be bad/inconsistent noob logic, but then they go on to call out the illogical parts of Lunatic's sus on you, and then assert in Post #56 that Lunatic is scum because his instant scumread (as B.K perceives it, more on this in a second) on you is irrational. Yet, they ignore how their instant townread on you would be just as irrational.
So it's not really that B.K's poor logic is the problem, it's the fact that they give so much thought to the idea of logic, EXCEPT when they make a conclusion. With that in mind, the fact that they instantly called you "town" and than instantly called the one person who disagreed "scum" reeks of buddying.
3. The whole "testing reactions" thing (as he claimed in Posts #54 and #61 looked legit to me for a bit, until I noticed how he did it. When he set up his "test" in Post #10, Lunatic didn't even respond to the vote itself (instead focusing on you), and yet by Post #19 they were already calling Lunatic "scum." While they gave a different reason than their "test" in Post #19, he makes it clear in Post #56 that Lunatic's focus on you in Post #13 was a failure of his "test."
Not to mention the fact that Lunatic didn't even say you were scum; he only said in Post #13 and reiterated in Post #29 that you COULD be scum, based on you being a noob. Was it dumb? Yes. But it wasn't outright saying you were scum, as B.K claimed.
It's completely unfair to test someone's reaction, and then say their lack of reaction is scummy, especially when the person conducting the test is exaggerating claims of "accusation." Again, one could chalk this up to poor logic, but for the same reason from earlier, I don't think that excuse holds up anymore. It's basically a test where Lunatic was damned if he did, damned if he didn't.
4. The idea in Posts #56 and #61 that Lunatic, Pie, and Supa are all somehow scum because they "baited" those three all into "uniting against" them. Ignoring the fact that they're basically claiming Pie and Supa also failed their "test," it is ridiculous to assert this game has 3 mafiosos, especially in Posts #65 and #69 after being told in Posts #62 and #68 how unfair a 5v3 would be. And of course, it's all to justify that idea that B.K somehow "baited" 3 players who made an observation that B.K might know a bit more than thought into failing his "test." It's all way too convenient. To me, it just looks like they're expanding their lynch pool.
So yeah, B.K has some poor logic, but it seems less like it's just plain wrong and more like it has a manipulative purpose behind it. At this point, it's more of a pattern than a mistake. He might be a noob, but I think he's a rather smart one.
As for the teammate, I suspect Badger right now, with a slight consideration over the other possibilities.
Yeah, I know, "YoU'Re JuST oMGuSsINg HiM," as if his vote on me is one of my reasons. Tbh, I don't care about that. Oh, no. I guess I can't have any reasons to suspect him because his vote happens to be on me.
1. Without any reason, he says in Post #9 that B.K reads as town. He is the only player here to say it outright. Admittedly this isn't suspicious on its own, but I have other reasons.
2. Also in Post #9, he makes the same vote choice as B.K one post later when they set up their "test." This is possibly an example of teamwork. It could also be that B.K is trying to buddy Badger as well, so this isn't suspicious on its own, either.
3. The big (relatively speaking) thing for me is the process of elimination, which is what makes the first two sort of worth talking about.
It could be one of the three B.K has in their scum pile as a sneaky way of not seeming too connected to them, but Lunatic and Supa have been way too skeptical of B.K for me to think that (especially Lunatic), and Pie was the one who first pointed out B.K's not-so-noob-looking interactions. I suppose it could be scripted for one of them (Pie in particular seems to have the least amount of suspicion on B.K when he normally is a bit more confident in those reads as I recall), but to be honest there's not enough to say so.
There's Earth, but they're inactive, and there's really no evidence to say they're lurking behind the scenes.
I did say there was a small amount of truth to Lunatic's suspicion on you, but it wasn't enough for me. That reasoning still stands. Besides, I think you're a bit more town now. The announcement of your research still isn't worth anything, but I like the effort your putting in; it seems honest to me, especially with the cross-examination you're doing. It could be all fake, but I see no reason to believe that.
So that just leaves Badger, who has a couple posts that make me draw comparisons to B.K. I know PoE isn't much at this stage of the game, but it's the best I've got given the other options.
TL;DR:
Best.Korea (Hard scum)
Badger (Slight scum)
Earth (Null)
Pie (Slight town)
Supa (Lean town)
Austin (Lean town)
Lunatic (Lean town)
I'm obviously most confident in my read on B.K, so I'm down to lynch.
