Job Training?

Are there really women this stupid out there?:

Prosecutors have indicted an unemployed man for sexually harassing women who were lured by an advertisement for lucrative part-time work he put on an online job site.

The man allegedly advertised online promising women W70,000 for working for three hours at a trade firm doing business with Japan. He took women who responded to the advertisement to a hotel and performed various sexual acts, explaining they should know how to entertain his Japanese clients before starting their jobs, prosecutors said.

The man backed the pretence by showing the women medical websites and using pseudo-scientific terms like G-spot. When victims became to be suspicious, he would abruptly end the session saying this concluded training for the day.

I’m curious to what the job advertisement said. I bet it wasn’t for secretarial work.
