I've done a first round of wagon-gazing. There aren't many occasions on D1 where more than two of the green names (including my own, from my PoV) are interacting with the same wagon, with the exception of a five-person wagon on e.
At its peak, the wagon is:
2.71828..... (5): mcmcsalot, LaLight, Robz888, Awaclus, WestCoastDidds
So given that it's stable for almost 80 posts, it seems pretty likely that at least one of e, LL, Awaclus or Didds is scum. In a "normal-sized" game, a fiver-person town-on-town wagon is significantly rare, but with so many players in here for D1, I would expect at least a slightly higher chance. There'd even be a case for there being one of each scumteam, if we have two multi-person teams. That seems kind of a stretch when we're only talking about six players in total, though, which probably means it would be smart to check the baseline assumptions about how likely it is for there to be a scum (or one of each scum) in a group of n players. I'll tabulate some numbers when I'm not so sleepy, but right now it's after midnight and I desperately need an early night.
Here's a description of how the e wagon came about, in case a summary is useful for anyone (and since I'd typed it all before realising that it might be more interesting for most people if I just to jump straight to the interesting part):
By around #200, e has had votes from faust and mcmc for a while.
Faust moves to Robz at #265.
Robz joins mcmc on e at #268.
Robz moves to Chicken at #361.
LL joins mcmc on e at #391.
Robz joins them at #402.
Awaclus joins at #473.
Didds joins at #482.
This wagon, the largest so far in the game at that point, stays stable till #561, when Didds moves off onto MiX.
mcm moves to raerae at #643, the the rest stay till Robz moves over to the growing LL wagon at #781.
