I see your point completely on this particular issue.
I wasn't aware of this dark underbelly but I have always acknowledged that the offed guy or masseur is taking a big personal risk going with strange foreigners to their homes.
We generally hear only of the risk posed to the customer.
There are many cases of females being gang - abused by mostly foreign Asian customers so the same can happen to the males I suppose.
Walking on Pattaya beach road a few nights ago I saw many groups of Indian looking men negotiating with single ladies of the night.
These ladiesat least know what they're dealing with before they decide to go but this is not the case with the boy in your story.
