100% true. There is SO much money in it, and there is a proven business model of teasing and scamming that the girls can point to.
If you pay attention around here it is the SAME tactics from model to model.
About the income, I dunno.... so many of them I don't see it drying up. Seems counter-intuitive but I think if it is drying up, going nude or doing sex scenes won't save it. When the interest is gone, its gone.
BUT... certainly the models are put in a position to decide if nude is the path to go.
Another thing to mention is that for every dude like us who want them to go nude there is a paying simp who DOES NOT want them to. The simps want to keep the girl pure like she's some sort of girlfriend / sister / family member.
