"I don't want to tell anyone what to do but they have to know they are destroying the industry," she added.
Shojai admits that she is also adding to the problem, with Instagram and Facebook accounts full of nearly-nude shots.
"But I think where mine is different is it is never full-frontal nudity and they are arty shots.
"I don't count being naked on a bed or with sheets as being nude I think it is just implied nudity," she stated.
Shojai claims models used to be paid thousands to get naked for the camera, and now thanks to social media it's much less.
"A lot of people need to save money these days and with all these women posting totally nude pictures of themselves - sometimes even with their legs spread - why would they need to go and get a nude magazine," she stated.
"But giving it out for free is destroying the industry."
She added that if unpaid women stop putting "sexualised" photos online, then paid models will be see as "valuable" once again.
