Correct me if I'm wrong, but your fos on Thor feels more OMGUS-y than anything. And as a newer player, I'd expect that from you. I tend to notice lots of newer town players fosing people that directly attack them since they know they're town and they know they're under attack. They think that scum is taking a bite at them instead of town being incorrect about them.
I don't necessarily agree with the case from Thor myself, but I don't exactly see the attack as a scum-motivated attack? Like it could be, but right now I just lean on him being wrong. Hence why I've said the interactions between you two are TVT.
Which leaves Rosske. I don't think his actions over the course of this game were genuine. I think he vote-hopped a few wagons opportunistically (Thor d1, KTS d1, Io d1, KTS d2, Transcend d2/3/4 etc.) I don't feel the votes he made were for genuine reasons, rather tactical ones.
I'll go over each of his votes that come to my mind in memory.
Thor d1: I think KTS was voting Thor at first correct me if wrong. Rosske's reason for voting Thor was pretty good (hence why I followed suit with the light bw that happened on him). However his actions a few posts later indicate that this was just an opportunistic scum-hop from him rather than actually scumreading Thor and it was him cherry-picking two posts and rolling with the punches. All he did to explain the vote on Thor alongside the 2 posts he quoted was say "gut". He did not pursue that wagon really hard at all.
KTS d1: I think Kcda (mhsmith) voted KTS. Rosske votes KTS as well. The reason escapes me why either of them voted KTS but memory serves that it was a bad vote. He never explained his vote on KTS to my memory, and the person who he voted with when he voted Thor was KTS. So Rosske never explains that his read on Thor changed at all, so he voted the person who he voted with without stating that his mind on Thor changed. Now this is the part I think is damning, but I'm going to safely dismiss this part as null for right now since it can go either way is him telling Karnos "Why aren't you voting Thor?".
Scenario B. He's scum telling karnos to vote Thor without actually voting Thor himself
Scenario C. He's town who questioned karnos' motives
Again all these scenarios are plausible, so it's best to dismiss that tell as null. But I seriously feel that Rosske was lightly pushing on Thor again and forgot he was voting KTS since he votehopped KTS and then gave no reason to why he voted him.
Io d1: IIRC he evades the KTS/Thor votes, doesn't explain why and then votes Io with karnos. One could say that he's town because why would he associate himself with his clearly ailing partner? There's many reasons why that can be wrong.
Reason B. WIFOM factor. "Oh if I hard buddy my partner they won't suspect me due to associative tells hehehehehe"
Over all throughout the course of d1, Rosske votehopped 3 times (to my memory) and his votes were all fairly neutral votes where he didn't explain his stance that well.
Now we're on d2. He doesn't participate in karnos twilight at all. Which was a period of at least 3 days. I understand that you cannot always be on mafiascum 24/7 but that was a long ass twilight period due to slow host. He posted
KTS D2: Instantly votes KTS. "You obviously bussed your partner". He says nothing else. He just sheeps what mhsmith/Luna Fox said in twilight for karnos. If you go back to d1 it shows that Rosske voted KTS, but he never explained that reason at all. Throughout either of his votes. So he votehops KTS twice and gives minimal to no reasoning both times. His vote on KTS doesn't last long. This is possibly the case due to him wanting the rest of the town to tear KTS apart while he WK's him and pushes on someone else. This person being yours truly!
Trans D2: KTS votes me, few posts later Rosske votes me too! This time he's been hellbent on my lynch. I think it's justifiable for players to fos me, due to my shitty reads and consistent mood swings. However, the reason this guy foses me is not genuine and sorta hypocritical. He has said that I'm scum for berating several people (which is me all the time as can be seen in several games of mine).He's also said that I'm scum because I've pushed several mislynches. The lynches I pushed for were Luna Fox (yeah this one was probably wrong) where he never said why my push on Luna was scum motivated, and him. I voted mhsmith Thor and Giga in brief periods but I've only tunneled Luna and Rosske. He said that I've coasted by getting several people mislynched. Which is blatantly untrue. I did not get KTS lynched, I didn't get PC lynched. I was advocates for two people. Luna Fox and Rosske only. But he explains that I'm scum for getting KTS and PC lynched. And say, that even if I did get KTS lynched here, why would he fos me for it since he voted KTS twice? This is inconsistent behavior from him.
With all this above and the 5 votes I recall from him being thoroughly explained, this is why I have concluded that Rosske is scum here. I understand you have meta townreads on Rosske, but Ross is a newer player and isn't going to play the same way as both alignments. Take a look at karnos for example. There were some parties (myself, Tenshii) who thought he was newb town. I had meta on him, Tenshii didn't. We were both wrong. We had incorrect meta, even though his game this game replicated the newbie game I played with him. Newer players are gonna get better and begin to play similarly as both alignments much like most of the good players here.
I know I have berated most of you all day, which was probably not the correct way to approach this. But I have for one final time, gone deeply in depth into all of his votes this game (which is most of his content anyways). And I've explained why it makes him the last scum, and why you should ignore meta this time.
