Gondor, Rohan, Elves (All of them), Dwarves, Hobbits. All of these are valid areas. Lesser known names hide out in all of them, though they are much lesser known in some cases.
About Spindax, AKA Qman: I also find his little knowledge weird, but not necessarily a scum move. Qman may seem to be delaying his responses and posting with little real info to be a lurker, but thats all conjecture ATM.
Matt_S has shown some Scummy behavior in the past. Now he seems just defensive, not very offensive in the Scum-Hunting way. I have not seen any recent votes by him or posts that actually give evidence for another players innocence. Possibly a response to early votes which caused him to retreat from outright accusations.
CoolBot has shown himself to be persistent against the bandwagoned players. Perhaps looking for an easy place to park his vote, perhaps genuinely believing in the Scumminess of the target. Even now, when Matt_S has explained himself, CB wants answers for answered questions. Perhaps he needs to reread, but he seems to want a quick lynch in any case.
Talitha also joins the Bandwagon, without much in the way of evidence, though none of us had much evidence. Now, however, she keeps her vote. She claims her vote can be easily switched, but I'm not sure whether or not thats the case.
Massive has gotten away with hanging back, IMO, but he hasn't seemed Scummy. He seems to be a valid Scumhunter and attempts to dissuade players from voting based on bad evidence.
Ting has shown himself to be Town. Not Scum, as some may still believe, but Town. Perhaps not a Power-Role, but not Scummy in any way.
eljcko almost seems to protect Matt or avoid him. Perhaps he truly believes Matt's innocence, perhaps he knows something we don't know. All I know is what hes posted.
That concludes my list, to catch up myself mostly. Argue with what you want. I tried to keep out my own views on who is Town and who is Scum for obvious reasons, some may have slipped. I believe I'm caught up now...
