Space?
Reading and thinking. The main problem I'm coming across is that there are cases on both, and both have clearly engaged in bussing. It makes me want to go for a tone read, but I already know that MiX comes out of those sounding scummy in a way that I'm not convinced is from alignment rather than just his norman thought processes. I still really don't like the way he kept insisting he's IC.
Anyway, while the various "would he bus if X" arguments are weakened bit by the clear evidence that someone bussed somewhere, let's look through that history.
MiX votes both Swan and then Chairs in early D1, but then never returns to them.
Chairs votes MiX from #278, through his 6-person D1 wagon, and doesn't move off till #369.
Even more interesting, at #369, ADK's whole wagon is just Swan and Chairs... it's unusual for scum to clump like that with no townies supporting the wagon, but i don't think I know whether the subject of the wagon in such a weird situation is more likely to be scum or town.
Around #500-#550, MiX and ADK emerge as leading wagons, with Swan on the slowly-building ADK wagon and Chairs on the slightly more established MiX wagon.
At the beginning of D2, Chairs goes straight for MiX, and MiX goes for Swan. I can't help but wonder whether they've talked about bussing aggressively in the scum QT and then just run with it.
In contrast, ADK is briefly on Swan in the middle of D2 (#927-#952), but ends the day not voting. That's worth a re-read.
Okay, re-read that snippet. It's interesting that Chairs's post of being "Firmly in vote: datswan territory now" at #953 immediately follows a post by MiX where he says he's keeping his vote on Swan because he's stubborn. Could it be two enthusiastic buses feeding off each other?
In D3, MiX and ADK
both vote early for Chairs. So again, we're definitely seeing pretty eager bussing from our remaining scum. ADK ends the day on-wagon on the Glooble mislynch, while MiX end the day on Chairs.
In D4, ADK does remarkably little (says me, hah!). Surely scum would feel under more pressure to be present and gain towncred?
MiX comes into D5 with "Good game everyone!" -- that seems a bit overconfident! Meanwhile ADK only makes 3 posts that day (to MiX's nine). Funny that in late D4, he suggested that maybe Chairs/gkrieg were using a lurking strategy to stay under the radar as a survival strategy.. all the while staying under the radar himself too. It feels almost too obvious, and also doesn't fit with the agressively-bussing Chairs we know we've seen in the game.
So yeah, it seems like I've kind of talked myself into the position that scum have been seen to have bussed pretty consistently and aggressively in this game, so I don't think giving MiX a pass just for his bussing is a good idea. Gkrieg tried constructing a scum narrative around ADK and didn't manage even though his survival more or less depended on it, which is also worth considering retrospectively.
