I've noticed something about Spiffy. I can't go back and check (there's actually no WiFi at my campsite, so I'm reduced to a phone) but let's take a look at Spiffy's lynching patterns, more specifically his timings. Day 1, the Cancerous lynch was extremely rushed, Spiffy being a large advocate, and HD was the second target. Day 3, once again, Amianki's lynch was extremely rushed and at the end, this also being on a very slow and inactive day. Day 2 was the anomaly here, where the scum HD was lynched. IIRC, Spiffy had been advocating his lynch all day.
So in other words, Spiffy has been "stealthing" the lynches by decreasing the users that are on at the time of the lynch target being really pushed. This is an interesting tactic for mafia to use, and can last a while without anyone noticing. Of course, I have to also address HD. I think that Spiffy pretty much betrayed his team for towniecred, and decided to satiate his own wants and needs instead of working as a team, something which I think he also did in Mario Kart NOC, where he was scum. This is why he was adamant to lynch HD the whole day.
