Coinbase Mt. Gox II Internet

Coinbase connected to my bank account, and took $426. They claimed that I could buy bitcoins from them, having been approved as TIER ONE, and in fact it appeared that a transaction took place. However, after receiving the money from me, they refused to honor their TOS, and instead suddenly said I would have no access unless I gave the copies of identity documents, which would allow any employee there, or anyone who has access to their servers (every hacker in Russia, for example) to engage in IDENTITY THEFT. I have been the victim of identity theft before, and the idea that I would provide EVERYONE in their company with my details, including IDENTITY DOCUMENTS, that would allow anyone who works there, or anyone who hacks into their computers,  to enage in IDENTITY THEFT, is a kind of  BLACKMAIL for access to MY OWN MONEY, and is CRIMINAL. It is criminal as their own website does not mention these documents as a requirement for Tier 1, for which I was APPROVED, the evidence  of which is I purportedly bought bitcoins.

It is actually a kind of extortion.

But, you say, they keep your information safe.

Do they?
