Well this extend I understand what went on. One time I asked for a db structure to implement a module for a hospital, instead of the structure they sent me a DVD with the whole db contents (means medical records of practically everybody in that town).
Is that "practical" export button and its default options...
When asked in the interview a couple days ago "Why did the auditor need access to the LIVE database", the response from MtGox was that they were auditing to make sure MtGox wasn't manipulating the quoted prices for sells and buys. In other words, gaming their own clients. That would be fraud. So, by MtGox's own admission, the auditor was auditing for evidence or non-evidence of fraud.
So it wasn't a DVD. It was live access to a database. It would appear that the access included tables which the auditor didn't necessarily need. And that MIGHT be (gross?) negligence...
Then again, what if the auditor was from a government agency? It might not be so easy to tell a government agency what tables they can and cannot look at...
