I'm absolutely astounded that anyone is framing the concept of taking advantage of the vulnerable and exposing them to this kind of material for such meager pay as an opportunity for them.
This is slave labor and exploitation, regardless of whether or not the person in question is or is not a child by legal classification and whether or not the pay is above average for someone in their situation.
It makes me sick to my stomach that we are once again achieving "progress" at the expense of vulnerable people.
