Provide evidence before you go making accusations.
I trust CoinJar with thousands of dollars in transactions and have never had any problem with them.
All transactions were conducted smoothly and efficiently without interruption. Their site is well designed and the security in CoinJar is evident with each update they make. Furthermore they're adhering to AML standards in Australia and use sms verification to assist in this process. If you are having problems, its more than likely you are attempting to scam them.
Now referring to your direct accusations of Zhou Tong, he is only one third of the business. If you took a moment to read through their site, you would see this, and see that they are backed by a team of well trusted professionals.
