Okay, advice.
Who do you think is scum? Let me give you some baseline information.
First, Mafia team knows who is on their team, which means their goal is to not get lynched and keep lynches on Town/SK. There is a need a eliminate SK, but it's secondary to staying alive. Maybe this game it's better to find SK early cause of the mechanic; I'm not really sure.
Anyway, staying alive means avoiding suspicion. Avoiding suspicion means making people think you're town, which means making people think you're trying to find Mafia (and other scum, but mainly Mafia). This is necessarily disingenuous because , well, Mafia knows who Mafia is, so it's hard to pretend to look for it.
Disingenuousness is detectable. Look for it.
I don't think it's Ash. Well, it could be, but I'd expect this from town!Ash as well. Probably not SK!Ash because as SK Ash plays more aggreeably and more protown than as town. Maybe I just gave some info away to scum team but hey I could be wrong.
Anyway, think in those terms. Who seems fake/constructed/forced with their posts.
