Sorry for that, guys. I got busier than I thought I would. Also, I apologize in advance, this will be a very long post.
As I went through the thread, I tried to think of who would be the most likely SKs, since obviously once the SK is killed, the town can only lose the game by it's own incompetence. Therefore, the SK should be the first priority. The clear number one choice I came up with Jdodge, which made me highly surprised to see that he was the one cleared of being a SK. Some of my case against him is applicable to him being mafia, but some of it isn't, especially the most damning piece of evidence, which was the day one mass claim. I'm going to post all of it, though, just to show my thought process of my reread.
In order to evaluate actions in mafia, you have to look deeper than the action itself, and look at the possible motives of the action. A lot of good can be garnered from asking oneself "why would X player do this?" When I ask myself who is helped by the day 1 massclaim, the only real player is the SK. Since this is not obvious, and is something that takes a bit of math wrangling to figure out, I don't think it would be "too obvious" a play for the real SK to do it. So we come to jdodge, there, who supported the plan even after it became completely disproven, which is really a nul tell for him anyway. The point was the proposition and cooked numbers.
From there, everyone else in the town left was basically against the plan, with varying degrees of vehemence.
So all that for naught...Sigh...
Then we have the whole argument with Ythill starting on post 185, where he is clearly in the wrong. He claimed that Ythill was a SK, and then gave evidence which was only consistant (in his view) with being a mafia member, while continuing to assert that Ythill is a SK.
His post 237 was another big point for me, both because he's hypocritical (jdodges nomal play style involves tunnel vision to the max, as evidenced in this game.) and I find that if you look at what a player states is scummy, you will often find that displayed in their own posts. In short, people define what is scummy from watching themselves play scum. And also because its a completely non valid attack. If a player thinks that two players are scum, there is nothing, in their own view, more productive than continually saying so. What jdodge asks here is basically "Pretend you don't find me suspicious, vote and pressure someone who you find less suspicious than me." which is completely ridiculous and scummy as hell...
So Jdodge has a higher chance of being mafia than most, in my eyes.
The next person I would look for, based on my own perceptions of how a SK would act, is YThill. This is because to a SK, any lynch is a good one. Therefore, I would expect a SK to keep their options open. To be willing to place subtle attacks and insinuations everywhere, so they could be blown into full-scale assault at any time. In addition, I would expect a SK player to hammer, when possible, because ending the day is good; it doesn;t matter who is lynched so long as that player is not the SK themselves.
Now, the player whos play this game matches that description near PERFECTLY? YThill. Ythill has sat on the fence the whole game, and attacked pretty much everyone at one point or another. If you look at his posts in isolation, you will notice that he has probably called each player "slightly town" or "slightly scummy" once or twice. He only seems to commit to "hard reads" on players when the momentum, and writing, is already on the wall.
Also, the "I waited for players to check in before I hammered so they are just as responsible as I am." is completely bullshit. First of all, you were the agent of action, not them. They did not hammer, you did. You are solely responsible for not giving A a chance to respond to accusations. I would expect an experienced player to do the exact same thing you did: Warn of a hammer immenent, and then hammer after a ridiculously short period of time after people had made a couple of cursory posts. That is exactly what you did, and the fact that you did it makes you more scummy, not less, in my eyes.
I'm just surprised that the rest of you did not pick up on it. Ythill is almost certainly not mafia, but is probably, given the FBI agent reveal, the SK.
Vote: Ythill
