Low moral principles. Acute financial need. Desire for easy money with the least level of discomfort. Desire to be the center of attention (exhibitionism). Belief in the accessibility of an easy, luxurious life with maximum freedom and independence. The same reasons as those encouraging prostitution. A virtual and non-contact way to engage in prostitution. In fact, this is the same work with the sale of your own life time and the demonstration of all the nooks that no one should see except the closest ones, the slow growth of cynicism and the abolition of faith in true (unsaleable) love. After all, in what area you spend more time, so you become strong and strong.
Of course, an elementary lack of funds!
And on such sites you can work from home (or any place where there is Internet) minimum investments (laptop, webcam, minor repairs in the room, makeup)
And most importantly, decent salaries of $ 1500 and above if you work at least 40 hours a week at night + a minimum set of knowledge of the English language.
In this area (if you work through an online studio) will teach everything very quickly - and elementary English, and how to behave in the frame, and what to say, when to smile, etc. There are even mentors (former web models) who will bring you to a financial result!
So one reason - a very poor population, lack of money, possibly the loss of the main breadwinner!
