Defensio for Facebook does a so-so job

The days when Facebook was nothing more than fun way to waste time with a few friends are long gone. Today, you're just as likely to run across prospective employers there as you are old classmates--and that's to say nothing of the scammers and spammers you might find, too. Keeping your Facebook profile and pages polished and professional-looking enough for all comers can be a chore, and keeping them free of spam and scams can be downright impossible. Enter Websense's TRITON Defensio Social Web Security for Facebook.

Available as a Facebook app (free for personal use; business versions range from $299 to $7,999 per year), Defensio is designed to keep your Facebook pages free of unwanted and potentially harmful content. It's easy enough to use, but is somewhat hamstrung by Facebook's limiting APIs.

You can activate Defensio by clicking its Facebook page and granting it permission to access your Facebook account. You can have it protect personal Facebook profiles or Facebook pages (such as those set up for a business or other activity) from profanity, spam, and potentially malicious content, such as viruses and phishing scams.

The problem is that Defensio's ability to protect a personal profile is limited by Facebook's API, which does not allow third-party apps to remove content from a user's profile: The user must delete the content him- or herself. That means that every bit of risky content and profanity--from relatively mild swears like "hell" to more offensive curses, like the f- word--appears on your profile. Defensio simply alerts you (at an e-mail address you supply) that suspect content, such as "possible profanity" has been posted. Unfortunately, Defensio's e-mail alerts (which you can turn off) always arrived a few minutes after the Facebook message telling me that a friend had posted on my wall. Because I had Facebook's own alerts enabled, that meant Defensio's alerts were only telling me what I already knew.
