Asians are not the only sex workers to be coerced, I think it's unfair to single them out. Most are here by choice to work a specified amount of time and make money to send home to help families or build a nest egg. I spoke to one recently who said she will be here 3 more months then return to China and be able to live very well on her earnings. I know another who has sent money home and showed me pictures of a very opulent condo she bought that her parents live in. The stories go on and on ..... one asian told me about the time she had a bodyguard accompany her to the money transfer place as she was sending 100K back to China .... cash.
Yes, younger asians may be more likely to be coerced, that's one of the reasons I am very comfortable seeing older asians I know are here by choice. And there exceptions to every generalization. But many other ethnic groups have coerced sex workers in Canada ..... not that this fact makes it right in the cases it is true.
As for the OP and subject of this thread, that's one fucked up system. Just as Chinese come here and have sex to make money, this loan collateral of nude pics is yet another example of what people in desperate situations will do to try to improve things. And of course young inexperienced women are making bad choices that they likely would not do if they had another decade of life experience. Sad.
