Ok, here's the reason for my initial vote on Eevee, I haven't completely had time to write this out.
Basically, I associate D1 Eevee with going off of his gut, rather than his head. There are multiple times where he's been able to nail me as scum (correctly) based off of a gut read -- Innovation, Monty Python Blitz Mafia, and Modern Community all stand out for me as times that Eevee used gut reads to pick out scum early (and these stick out clearly to me since I was on the receiving end of these gut reads). To me, a typical early D1 Eevee post is something like "Hey guys, I'm following around, I don't have any strong reads yet, nothing has stuck out to me", etc. etc. etc. I got a completely different feeling from one of his first posts of this game (which I will quote later), and it reads scum to me.
I just went back to look for comparisons with his most recent scum games (Game of Thrones, Mean Girls). Let's quote early posts from those games here:
I think the only game MGP is in is still ongoing, so actually no, we cant' give you a rundown.
Ashersky, "super towny" might be bit of a stretch about your play in bankers beware..
Actually these longer "more analytical" posts (which I find better as a town playing style) are actually a trait I attribute to scum ashersky. Vote: ashersky, only semi-rvs.
This quote is from Mean Girls, where Eevee was scum. Note that Eevee did not know that Ashersky was scum in D1 of this game, even though they were partners (Yuma or Eevee, correct me if this is wrong). This was about his 9th post of the game, but the ones before that were mostly involved in theory.
I'd like to plob my vote down somewhere. Walrus's flipflopping on faust sememed like he wants to please the crowd, first finding him scummy but then changing his mind when yuma (?) voiced criticism on his reasons. That's more mafiay behavior in my opinion, especially a newer mafia would want to blend in with the crowd.
vote: walrus
This is one of the first posts from Eevee in Game of Thrones, where he was also scum. Probably, again, about his 10th post of the game -- there were a few talking about theory (should Bulletproof Townie claim), and then a catch up post where he posts a few reads, followed immediately by this post. There's a similarity with the last post -- an identity of a scum trait, which he attributes to a player, then voting that player.
Vote: TwistedArcher
It does help to move the game towards social deduction if people start voting. This is unfair because TA really made some good points, but the way he laid them out, all sense-making and noncontroversial, is just how scum likes to blend in in my opinion.
As I get more experienced with mafia, I too am starting to suffer from a case of Robziaitis, which is caring less and less how others view you or your alignment, and more and more about just doing what you think will work.
Now, this is the post from this game that I found scummy. There's some similarities with the previous two posts, again - it's an identity of a possible scum trait, followed by attributing that trait to a player, then an early vote.
This is VERY different than the early town meta I associate with Eevee, which is him trying to get a "feel" for the game early on. There are similarities between all three of these games -- two where Eevee is scum, and this game where Eevee is unknown. His reasoning, identifying "scum traits" early, rather than having a "gut read" on a player (which I associate with town Eevee), is something that I think makes Eevee to flip scum here.
The next step, of course, which I haven't taken, is to go back and read games where Eevee was town, and see how exclusive this trait is to his town games, if at all. I will hopefully get to that soon.
