You suggest you to provide both a valid collateral and a proof you're SwingFirst account original owner, by signing a message with the following BTC-address from unedited past posts: 1DNwZfpCYkmPP82xty7HThv9ngadjQa2T2.
I labeled my bitcoin address "SwingFirst - May 18th 2015" to prove that it's still me and that this account is not bought. I don't use this account regularly, but I am the one who made it almost two years ago.

A signed message with your BTC address would be much better..just saying.
AFAIK Blockchain needs a signed message from the address to add a label.
