No reasonable business "release half the information to the suspect privately" there is no need to give a suspect 12 hours advance warning on how to craft his fabrications.
You're right - no reasonable business would release that kind of information at all because if they're wrong they're going to get sued.
You seem to have been able to whip up quite a few interesting and compellingly contradictory stories in 63 minutes, what would you do for the other 10 hours and 57 minutes? Perhaps create a couple of more identities for you future scams, or develop 17 new websites to fleece people out of their money?
If you've lost a lot of money in this, I can understand why you're so angry but what you're saying right now is you're absolutely, 100% certain he's done this. Without a shadow of a doubt, you know he's a liar. You conclusively know that he's stolen all the Bitcoins and cash. If this is the case, why don't you call the Australian police yourself? They would be able to locate him within a few days, possibly a day considering the sums at stake here.
You fucked up, and abrogated any consideration of privacy.
This isn't true even if he's guilty.
You created a cluster fuck of a gambling system, ran it illegally as a minor (or ran it illegally under an assumed name without due process) got caught up in it and bailed out to some gangsters who thought they were smarter than you.
I wouldn't go as far as to call exchanges gambling systems any more than I'd call a kitchen knife murdering equipment.
Sorry sonny, but you decided to make this a public (and obviously fraudulent) mea culpa, and you have absolutely no right to any claim of privacy. You decided to shit this all over the bitcoin world, and now you will sit back and suffer as the whole bitcoin world brings it back to you. You will be investigated, you will be charged, and you will be held accountable. Whether you are some Obama loving otaku pinhead, Notorious Relic Dealer Chen's right hand coolie, or just some lonely, unloved ex-pat student struggling to makes ends meet pimpin' between Singapore and Australia, you will be found, you will be brought to justice, and you will learn the consequences of your actions.
Whilst I accept that you don't believe there's even the remotest possibility that anything ZT has said is true, imagine for a second if you will that he's eventually cleared of all these charges and it turns out that Chen does exist, how will you feel about saying all these things to an innocent minor?
