Alright, on the note of Machamp, perhaps he is trying to frame you if he is not telling the truth? As to draw comparison, I consider myself to be quite clever, yet I make many mistakes. Everyone make mistakes. Even Einstein made mistakes. Saying someone is "too smart" for something is just plain ignorant. (No offense) A wolf woldn't directly come out and put themselves in the spotlight by contradicting another story, that puts them on the suspect list, especially for someone like Machamp who previously had no been extremely suspected. Everyone makes mistakes, yeah, but if someone is making up a watcher role, they'd probably watch out for not making contradictions, that's why I think that it's entirely possible his role was weakened, or some other strange thing happened. Since there is, from my knowledge from looking at Dark Void's post, there is only one wolf left. These are overwhelming odds. It is a completely possible cover story to say "hey, I am a watcher. No one targeted him last night. Let's lynch him." and when you turn out to be town (If Machamp is the wolf, that is) Machamp could say "Hey, bro, my role must have been weakened or something, man. Totally innocent". And when you say that a wolf wouldn't do such a thing, you are correct. I know from my past experiences -- as I have been a wolf in both the Dusty Gulch and Canton Falls games -- wolves don't do that. Sorry, scratch that, logically thinking and not desperate wolves don't do that. You forgot to compensate for desperation in your calculations. When someone is desperate, they come up with some pretty crazy stuff. Just look at me from last game: I said I was a mirror salesman.
Then there is the case of you. I still am not even 75% sold on your innocence, and the fact that you seem to bandwagon on most of your posts makes me think twice about marking you off as town. So, you could, in fact, be a wolf who can see roles as well as role block. Actually, I'd have to be a wolf, be able to steal a role, and be a role blocker. In my mind, that role is way too OP and very unlikely. Secondly, I hate playing at he beginning when there are a million people alive to I tend to post/ bandwagon to stay alive. I don't have the time to analyze the game at the beginning. Most recently though I've been analyzing the game, first by opposing the lynch of Bippa (By all logic at first a half-seer wolf was unlikely and I didn't believe it), then acquiring an important role of my own, using it to confirm information about a wolf who was becoming clearer by the hour, and using it to cofirm a townie. Alright then. I get your reasoning. I try to post in the early parts of the game, too, but sometimes it is way too chaotic. Especially with everyone going "No Lynch".
These are just my opinions, and I haven't any proof to back this up. However, my gut is, more often than not, correct.
