AMC isn't even a company, it is only a unit under VMC. How could it be approved for public trading?
Most sites just charge a fee and you are listed. Your contract could say that you will use the money to 'Kill Whitey' and you could still be trading.
I had thought BTCT.co would be different as they do have a review process, but they failed miserably in this instance. It looks like buyers there lost 750 BTC in the last 2 days so maybe changes will be made.
More likely not though.
