How to Recover Hijacked Friendster Account

Just got this in the email:

“my friendster account was lost…in short, it was hacked by anybody i dont know… is there anything you can do to help me? coz he/she changes everything, log-in i.d, pasword,and changes my settings including pictures, bulitens that are very downgrading and immoral.please help depressed with whats happening to me.. ”

First question that comes to mind is how can I verify that I got the email from the REAL owner? My guess is that Friendster will be asking the same thing? If everything was changed, how does one verify true ownership of the friendster account?

Please feel free to jump in and share your ideas here.
