FFS, they are reaching now. This basically means they are asking you to provide a notarised copy of an undefined 'declaration' (Bank statement?) which supposedly shows where the original fiat funds came from before they were used to buy bitcoin. It appears they actually want to see the transaction details of the original deposit amount they were sent.

Yet another prime example of how there is clearly a concerted effort at BTC-E to deny people access to their funds under the guise of onerous, and largely arbitrary, AML and KYC rules which are not being applied correctly or evenly.

As has been mentioned already, it is entirely possible that this procedure whereby they keep requesting more and more details and ID documentation from their customers, is both a way to deny access to those locked out of their accounts and accumulate a lot of valuable Identity data.

These people are not Kraken, they do not have a public presence anywhere outside of electronic company registers and virtual offices. There is every reason to suspect nefarious intent with regards to the collection of so much information from customers they likely have little intention of making whole.
