I'm curious why, given the prior reports of security issues at Coinbase and the ongoing drama with Mt Gox, you guys didn't immediately hire, say, tptacek's company to do extensive penetration testing and a full security audit. It appears that not all API calls were rate-limited, as they probably should have been, and there certainly doesn't seem to be any sort of monitoring of brute-force attempts like this in place. With all the negative publicity around Bitcoin exchanges, you should have doubled down on security weeks ago, or at least explained the privacy tradeoffs in your design decisions clearly.
