Assuming this is true, it only explains why some people would traffic kids (to make profits), but it doesn’t explain the motives behind the sex itself.
For example, if you told me that eating fecal material from midgets from mars was highly profitable, I could understand why one would be a seller of Martian midget dung, but I still can’t understand why people would eat it.
Anyhow, this is creepy shit that apparently happens with defenseless people. Perhaps we need to make children not defenseless.
