Dr. Greg is not available now so I'll provide an initial response and he can add to it later if he wishes.
At MKL we provide the resources for you to do your own due diligence prior to accepting a job. Between our checklists, articles, and forums, you should be adequately equipped to determine if the position appears safe enough to consider accepting a position.
As you can imagine, given the numbers of viewers, we have no way of individually contacting schools, determining their fitness and responding back to each poster about his or her school inquiry. This is an uncompensated volunteer effort that, as it stands, already requires considerable care and feeding.
Our purpose is to provide the readers of our site information to equip themselves adequately to avoid the many traps and pitfalls in China ESL employment. If you have diligently read and followed our writings, you'll not go far wrong.
I would urge you to check out the resources we offer, and having exhausted them, submit any specific questions or concerns you may have to Dr. Greg or myself.
