My instant reaction was that this email was a phishing attempt. But as I read on I saw it did not ask for my account details or to reset my password using a link it provided.
Then something else struck me: the only way Hint.io knew my personal email address,that I had an account with Gawke, and my account information had been compromised, was if the staff at hint.io had access to that stolen information.
I've emailed firstname.lastname@example.org asking for an explanation as to why the hell they have a stolen password database.
Hope they have a really good explanation.
Just like I hope Gawker has a good explanation why account details were stolen, why they didn't inform account holders themselves, and why their password reset system has gone down.
