It is easy to beat the scammers by changing your password securely - It's little different than registering.
All anyone has to do is log on with current password - TOP RIGHT OF PAGE. "MENU" BUTTON WITH HORIZONTAL STRIPES.
Click on the MENU button and then click on ACCOUNT SETTINGS - There your will see the option to change your password SECURELY.
Or you can click on the link below that will take you to setting. Where you can change your password without fear of scammers.
