i see no point in this really, how they are going to know that someone is not telling the true, it's easy to say the false, for the question "how you obtained your bitcoin"
other question are just destroying their privacy, like why they are withdrawing , which again can be false
if what we are reading here is the truth not the obfuscated version of it by a click-bait news site then it is just going to push people to OTC trading. and it was discussed before and some people warned the PBoC about this. and eventually you see the volume go much higher and price much higher because they are buying through other channels. and finally may lead to change of rules they put in first place.
