Thanks Joe. That's pretty much exactly the sort of explanation I was hoping for. I personally don't really need to see a full claim from you, I was just puzzled. But thanks for clearing that up.
Concentrating on Vitek's summary now, and I think I'll try to make a case for each. I pretty much agree with the facts as presented (except obviously, I count myself in the town pool due to being town).
Between the four remaining presented, I have to say that Twilightbard's behaviour still really bugs me, with every reason I gave on D3 plus particularly his pressuring of Joe. Plus I have a slightly crazy theory too. Obviously TB should still get another chance to respond. Tread lightly, pal.
Stuart has been very background and quiet, and has done next to no scum hunting since Day 3 began (and he wasn't exactly throwing himself out there on day 2). The towniness I pinned him with on day 1 has long since worn out its welcome and I'm starting to think I confused learning the game with acting town. So yeah, I'd like to see a little more proactive behaviour, and I'm going to be keeping a close eye out.
Itai has been making weird posts, disappearing at critical moments and being generally lurky. While there are moments when he seems to actually have an excuse for not posting (end of D3), there are others where it's obvious he's around but just isn't taking part (quick one line posts unrelated to discussion (bit on Crazybear's lynch for example)). While not necessarily scum, he's got a somewhat town unfriendly style (seems to know a lot, never really shares). The desire to preserve Muttly is kind of a plus for him though.
Robb seems fairly straightforward. I personally don't notice a lot of scummy behaviour EXCEPT for his hammering habits. The hammer on day 3 was not well handled, and cutting things off without a chance to hear from others is not a good play. In addition,
Post 873 struck me as kind of odd. He seemed quite reluctant to swap, saying that switching to Pazzer didn't make sense as there were more votes on Twilightbard. It was a line of thought that didn't really add up, and he acted like the thought of getting one more person to vote for Pazzer would be impossible compared to two more votes on Twilight. Attempt to protect his scum pal? It can skew that way. I don't think it's the most solid case but it keeps me from being willing to just peg him as town.
Right now, here's my list from most scummy to least
Twilightbard (contingent on his next post)
Itai/Stuart (very similar behaviour)
Robb (only minor issues, but still issues)
Alright, I have more crazy theories to follow up on so I'll keep my vote handy for now.
