Be warned that there's another Facebook scam going around today: compromised accounts are sending out links to a site named "ponbon.im", as shown in the image - do not visit this site. Our guess is that the attack is using accounts that were compromised previously - if you receive the mail, simply delete it without visiting the link.
The advice to avoid having your account compromised remains the same: make sure you run an up-to-date virus scanner, keep your OS updated, make sure you're running the latest version of your web browser and do not enter your social networking passwords on third party sites.
