Like email spam, one way to stop Facebook spam from spreading is to learn about spam, malware and phishing messages. Know how to spot them and also familiarize yourself with how these Facebook spam messages work.
One of the most common types of Facebook spam is a Wall post that encourages you to install a Facebook application. The application will require that you to agree that the application can post to Walls and your Facebook friend’s pages. When you allow this authorization, the spam message is immediately sent to your friend’s Walls. If a friend sees the message and performs the action, he or she will then see the same spam on their Wall and the cycle continues. This is how spam messages can move so quickly through Facebook.
Unfortunately, many of these messages are designed to trick Facebook users into cutting and pasting malicious code into the address bar in the Web browser or by clicking an embedded link in the message that takes you off Facebook (commonly through a URL shortner link) where you could potentially become victim to malicious malware and phishing scams.
