Maybe Dolby is. I cannot guarantee that if he’s actually mafia, that it wouldn’t be his true intention to actually focus more and kill townies specifically. From what I’ve observed, he tends to ask for answers from everyone, more so from the frequent posters, and attempts to get the AFKers back into discussions. Maybe you’re onto something legitimate after all.
As for Dino and Ribbit, it’s entirely possible that Dino was tasked to place a vote on D1 by Ribbit. I have both on my sus list for different reasons, so I could see that scenario actually happening. I currently still lean on ribbit more for wolf, as I’m still very unsure about Dino.
