I can say most members simply ignore guest counts over member counts when it comes to spending, we only look to other members in a room.
In my experience this is not entirely true. When I first joined MFC I put "top models" at the top of my display and frequented those models with more people in their rooms thinking they had to be doing something "extra special" in order to have that many people in their room. I now know different, but this knowledge didn't come to me overnight, and I suspect that somewhere there are some stats that show that this new botting phenomena has some sort of positive effect on a model's/studio's earnings. Else, why would they be doing it?
