How can you protect yourself in Social Networking sites?
	Limit the amount of personal information you post - Do not post information that would make you vulnerable (e.g., your address, information about your schedule or routine).
	Remember that the internet is a public resource - Only post information you are comfortable with anyone seeing. This includes information in your profile and in blogs and other forums. Also, once you post information online, you can't retract it. Even if you remove the information from a site, saved or cached versions may still exist on other people's machines
	Beware of strangers - The internet makes it easy for people to misrepresent their identities and motives. Consider limiting the people who are allowed to contact you on these sites. If you interact with people you do not know, be cautious about the amount of information you reveal or agreeing to meet them in person.
	Be skeptical - Don't believe everything you read online. People may post false or misleading information about various topics, including their own identities. This is not necessarily done with malicious intent; it could be unintentional, a product of exaggeration, or a joke. Take appropriate precautions, though, and try to verify the authenticity of any information before taken any action.
	Check privacy policies - Some sites may share information such as email addresses or user preferences with other companies. This may lead to an increase in spam. Also, try to locate the policy for handling referrals to make sure that you do not unintentionally sign your friends up for spam. Some sites will continue to send email messages to anyone you refer until they join.
