TheBeijinger.com and Shexpat.com also runs ads for the China ESL scam and bunch of other shady agents. Money is money and they will never turn it away. If you have an ounce of brains between your ears, you will ignore these ads and apply directly to the principals of the schools.
BTW... their own forums are full of horror stories about the scammers that advertise with them, so don't think they are in the dark. They clearly know the score friends.
