Probably phishing. Why would you make a mirror, when everyone can use the official site? :-/
One way or another, stay well away. Seems phishy (Geddit)
I'm guessing the domain name or IP for bitcointalk.org is banned in other countries and this mirror provides a portal for foreign readers. I'm investigating whether my original password was possibly stolen for different reasons. I have changed my initial password BTW.
The mirror is hosted on cloudflare out of California and using their SSL cert. Although the domain owner is hidden, it's someone out of Panama.
From what I can tell so far, it looks like they mirrored this site but did not take any of the PHP forms with it. They also don't use any javascript beside a Shopify stat counter at the bottom of every page:
• The login form from the home page uses PHP to POST a "user" and "passwrd" value to fanbitcoin.com/index.php?action=login2, the same behavior as bitcointalk.org/index.php?action=login2
• Bitcointalk then uses javascript to process the "user" value "frmLogin" See
