As far as chairs goes. I think he could be either scum or town. The only thing we have so far is that he is anti-claim
First of all, it is clear that everyone is given a name. That name also has a direct correlation to your status as town or scum.
scum reasons to oppose claim: You were not given fake-claims. You will have to do some work to figure out a good fake-claim, then hope no one counterclaims you.
town reason for opposing claim: You believe it will out PRs.
Now, I do not think that the town reasoning is solid. I think that both VTs and town PRs will have names that are indistinguishable from each other. Further, the town reasoning against claiming flavor is not really awesome either. Again, I believe that VT and PR names will be somewhat indistinguishable. Since we merely disagree that town would oppose claiming, I do not think that it is enough to say that chairs is scum yet, but I am suspicious.
Now, another reason town might want to avoid claiming is because you also believe that scum have fake claims which makes the exercise pointless. This is entirely false. What this is doing is forcing everyone to get an opinion down. Either anti-claim, pro-claim (not claimed), or pro-claim (claimed) that we can use later to figure things out.
