The complete case on pingpongsam.
1) The claim.
He drops hints that are impossible to overlook D1 that he is a Cop and wants to target TA. He survives N1. Then for a long time, he does not claim anything, and a wagon builds on him, which is the only wagon on that Day so far. I point out that I'm assuming no Cop claims that Day, because it is already late in the Day. Following that, PPS claims. The reason he gives is that he wanted to give credence to TA and people to discuss his scum read on Eevee. Also he saw what I said and thought he should claim. This seems just a strange reason to claim. If you're a town Cop, claim when it seems best to you, not when other townies think you should claim. It feels like he was willing to wait until L-1, but then got scared that if he did, we wouldn't believe him anymore. And the whole TA thing - I think if you're holding back your investigation results, it is to hear other player's reads on your target first. But PPS never enforced that. Lastly, when it is pointed out that he shouldn't have breadcrumbed, he says he was just being "sincere" and then realized this was bad. Well, I expect better play from town!PPS.
2) The "good" voting pattern
I stated D3 that it is notable that PPS has yet to vote for a confirmed townie, stating this makes him more likely town. PPS follows this by giving me a town read and sheeping my scum reads on AHoppy and Archetype. He also states a conviction that Jimmmm is town. Guess what? Jimmmmm dies the following night, and PPS comments this by stating "well, my reads are spot on" and voting AHoppy at MyLo. Not concerned that scum is just messing with you, trying to exploit your thinking that you have good reads?
3) Town reads on players who have town reads on him
This is only a minor point, but at least twice in the game, he has given town reads to players shortly after they stated that they think he is town. This happened with yuma D2 and with me D3. Looks like buddying.
4) Does not give good reasons for his vote
He is after AHoppy since D2, but never really laid out what makes him think that he is scum. On D2, he reasoned with the wagon on AHoppy. On D3, he said it was a PoE thing. On D4, he states that he is confident enough in his reads to vote AHoppy.
5) Jimmmmm's death
The mafia played pretty straightforward with their night kills, I think. N1, they killed Voltaire, N2, they killed yuma. Both players with traditionally good reads who were pushing the game along. The main forces pushing the game along D3 were Robz, PPS and me, I think. Why kill Jimmmmm? They must have thought this is in some way of benefit to them. And who used Jimmmmm's flip to support his argument? Right...
6) The scumminess of TA
This probably deserves a post on his own. TA is in my eyes not acting like the quasi-IC he claims to be. As IC, you know your reads are probably worse than those of everyone else, so you listen to other players, ask questions, and try to push the game along, only throwing in your opinion when needed. This is not what I saw TA do. Instead, he fervently pushes a case on me - a townie and claimed Cop - even going so far as leaving me to be quickhammered by scum. And if TA is scum, obviously, so has to be PPS.
7) Cop distribution and scotty's townieness
The obvious thing last. There has to be a liar among the claimed Cops. It's not me. scotty I see as a townie player, and if you don't - he's still a newbie. Do you think he would pull this kind of genius fakeclaim just like that? I don't. So by PoE, PPS has to be the scum.
