Sorry, I was logged into the wrong account. Yes, I work for Blockchain.info and rejected this API key request. I wanted to post here to let people know that this is clearly a scam site.
Ouch! Well there it is BC.info does not like the HYIP games. I'm pretty sure you could classify all these sites on the same category though. Can OP reply to this? Is he shutting down or looking for a new API provider?
