It's not a legit. It's a phishing site. Since you've failed to log in, you've already sent your account details to the malicious entity behind it. Change your credentials immediately or you're going to lose your account.
You may also want to change passwords to other accounts across different sites with similar usernames if you use the same password for them.
OMG ~ the whole site is duplicated.
Thank you !! I've taken the necessary action to reset my password. Glad that my username is only used in this forum.
