After being in a relationship with someone who had been dumped by their former husband with no money, I can certainly see how someone foreign and poorly equipped to navigate Government support and the job market for good, honest work, can be enticed into and fooled into thinking it is the only way to survive. This girl was from a good family, and had been in a well-off relationship with kids etc and had always worked in low-skill jobs, but on her own with nothing and no-clue, and a bunch of Thai "friends" trying to lure her in, it's easy to see how someone with good morals can get trapped as a matter of survival.
