We're still not even halfway through D1 so I don't think a lack of activity is that indicative of anything tbf. I'd rather look at the fact their total of 3 posts came within minutes of each other as a sign that they are either not really that worried about the game or genuinely very busy
Now a lack of worry can be read in different ways, it could either be a Town like behavior, where D1 is usually perceived as a lost cause due to grand lack of intel about pretty much anything (unless a Scum hard slips)
or it could also be a scum tell if we assume the game state is favorable for Scum, which it kinda is right now cause nothing is really happening.
Personally I'd slightly lean town in this case cause what little they've done doesn't seem to have any agenda behind it.
