Precautions while using Facebook
Never use the same passwords
Never use the same passwords that you use at work on a social networking site. Try to avoid mentioning where you work; so that if you mention something you thought innocent (but that might be valuable information for hackers) they will not know who to target. Be wary of what youre posting, if you use your pets name as a password anywhere do not post about it on your social networking sites naming it.
