I think we should start with this scum.
My Reasoning:
1. AV's post timing - He posted this just after the time he would have gotten a PM, read it, maybe posted in PM (20 minutes from fetch's post)
2. TP Special PM vs. Scum PM - If AVs PM was that of a town special IMO there is no way he WIFOMs being SK as that makes him a number one target for the MK
3. Why do it as SK? - I think AV is bold enough to make that claim as SK (I am not sure he has ever been one) just address it jokingly because it's there and move on, hiding won't work in this game, that being said since once again it makes him more likely an MK target I think mafia is more probable
4. Mafia is most likely - Why do it as mafia? IMO AV would have several reasons to post an SK WIFOM - first it deflects from his true alignment, may give info about who actually is SK with responses to it and finally he doesn't fear the MK.
IMO this is the most concrete thing to base a vote off of unless Ceres is telling the truth about his investigation on SS.
Vote AV
