I'm catching up by 100-post blocks since it seems to be a bit easier that way:
First of all, my ABC townread is heavily based on this page. He's pretty aggressive, which means that he's been proactive in finding scum, and has also been careful to direct questions at people who are most qualified to answer them (his question to radish was about modding, his question to prof and linkz was to double check that his suspicion was valid). He was also the first to throw suspicion on the Captain America claimants, which I definitely don't see scum doing now that enough sidekicks to the same hero have been claim, simply because there's no reason to. They know that not all of the claimants are lying even if one of their buddies decided to throw a claim into the mix, so it's better just to keep your mouth shut as opposed to tossing in some half-baked suspicion into the mix.
Miz read is based on similar reasoning, although it's a little weaker. He's been a little cagey with his reasoning, which I don't particularly like, but he's been proactive in applying his HoSes and has a pretty natural transition from HoS'ing to Yoshiya to actually voting him. He was also pretty quick to attack Stefl, which seems decently odd for a new-scum to try during his first game.
Stefl is town because of early game aggression and the Captain America sidekick counterclaim. Stefl was the first one to discover that there were duplicates of sidekicks, and I seriously don't think scum would point that out even if they do have safeclaims, simply because it isn't worth the risk of being outed that early.
