Well, if I were to follow your train of thought - are you from the civil service? Do you have authority to say that you're "pretty sure it doesn't just work that way"?
Things on the internet carries an implied condition that you take it as it is, and to rely on it at your own risk. No one denies that. All online discussions will grind to a halt each time qualifications must be produced in order to say something.
Sure you may cast doubts on the accuracy of the statement, but I don't think that it should be done in the manner you have done:
"Vince - do you work in the civil service? Does this Mr Wang of yours work in the civil service? Or simply just armchair critics/ disgruntled people sitting on one side just whacking? I'll just wait for the civil servants to come in."
If that was indeed your point, why ask me or Mr Wang whether he works in the civil service? Even if one works in the civil service, he/she may not have such information. Couldn't it have been better put as:
"It remains to be verified if the points raised by Mr Wang are authentic - is anyone able to verify this?"
