I notice in the article CNN report that the person who was impersonated stated

"All Internet users should be aware their identities can be compromised, and "every user of the Web should be better educated,"

Sound advice.

Although Facebook has excellent optional privacy settings (but only if you use them)it is important to be careful just who you 'confirm' as a friend, although simply checking before you click is usually sufficient, otherwise you are at risk of not only divulging your own personal details and photos but those of your genuine friends as well.
The same advice is even more important in an open forum such as this which has also suffered from imitation and impersonation of its members.

Useful information from Facebook
"What should I do if someone is pretending to be me?
If someone has created an account to impersonate or imitate you, please go to the impostor profile (timeline) and click "Report this Person" in the left column. Check the "Report this Person" box, choose "Fake Account" as the reason, and add "Impersonating me or someone else" as the report type. Be sure to add a valid web address (URL) leading to the real profile (timeline), so we can review the information."
