To make personal information invisible on Facebook

Facebook is good platform of communication, and most people like to share their experience on it. However, not all can be posted publicly on Facebook, for example, cash. A young Australian girl who posted a picture of a massive pile of cash to her Facebook account and was then shocked when, just hours later, two robbers have paid a visit to her house. This girl was helping her grandmother to count her savings and she decided to take a picture of what she herself described as a “large sum of cash”. The image was just posted on facebook, hours later, two masked man rush to this girl's home in south-eastern Australia. Fortunately, this girl was in her grandmother's home in Sydney at that time, only her mather in the house. The pair couldn't find this “large sum of cash”, but took small sum of money and some personal stuffs, such as iPhone, as well as some cheap Apple accessories from the home. Nobody was injured, luckily. It is not clear that how the pair locate this girl's house by using facebook. Maybe she publish her details online. But we learn from this accident, sharing detail personal information online is really dangerous and bad idea.
