I've never advertised on-line to get a position, so I have no useful information about that activity. The American may very well have bogus credentials, but on that website I am unable to see where he claims to have graduated. Ozzie, however, trumpets his higher institution of imagined learning. Distinguishing between obvious guilt and potential guilt is not, in my opinion, splitting hairs.

In China, if your credentials are adequate, deciding the city and the universities where you prefer to work and contacting them directly seems the best procedure and in my case has always been successful.

At EACH Chinese University where I have taught (4) there have been individuals with bogus credentials, one Masters Degree, three Doctorates. Additionally, EACH university had several 'stealth' missionaries who were teaching and surreptitiously proselytizing, one transforming his Doctorate of Divinity from some fundamentalist on-line degree mill into a 'secular' PhD.

Water into wine.
