These are some tips:

Be careful when using friendster in "not trusted" computer shops. They might have keyloggers that registers the username and password that you input in the computer.

Another thing, log out before you times runs out because when a new person opens the same computer you used and your account is still logged in, "BOOM". They can make use of it.

I searched the net and I found out that there are people who demand payment in exchange for hacking some else's account like friendster, multiply, or even the yahoo mail account.

There are many downloadable programs that can force websites such as friendster to give the username and password. I downloaded one but there are these weird code thingies that I have no idea what. I guess only a pro can use one.
Be careful guys.
