One thing I don't understand is that we know all about this and we know where these people work.
Here in the US, they work in "massage" parlors -- which are listed in the phone books.
I guess if we really wanted to stop this trade, these places wouldn't exist.
Those who hold women against their will to do such things should be treated as murderers and more--they first remove the woman's life to live as she choices (murder) THEN replace it with this sick work (the more).
Concerning massage parlors, they are obvious--they are advertised next to strip joints in newspapers!! Man, that sickens me whenever I see it. But I believe there is a more willful nature to what happens here that is lacking overseas and therefore some people don't consider it much of a problem.
I'm not surprised the government is doing little to counter it. Governmental actors are apathetic to all but the most severe crimes in violence or cost. But I am surprised that people, particularly religious groups (not the sanctimonious religious of the liberal persuasion who twist religion to fit their lifestyles), haven't taken to protesting these places and taking pictures of those who enter and making the pictures available to the public. That would be humorous.
Here, LE works pretty hard to suppress the streetwalking trade. But rarely do they bust a massage parlor or the internet trade. Seems to me they just want to keep the trade underground so they don't get complaints from neighborhood groups and businesses.
