Well, the title in itself would have conveyed the meaning and just as it reads, crime is something that can be committed and traced throught Facebook. Though the social networking website has helped cops crack several criminal cases and reopen several which were once considered dead and closed, the fact that the social networking site would help criminals too is something that needs to be given a thought about. Owing to its popularity and the large number of members in it, criminals find it a very convenient place to start off their next burglary operation.
And to explain this I would give you an example how they might approach you. They would first give an add request with a rather good looking gal/guy as their display picture (which of course wouldn’t be them). Once you add them, the operation begings there; they start looking at all your pics and get to know what kind of a person you are in the society and the things you would be having at home if you had posted pics of your home party. Once they get to know that you are a potential target, they start doing their research around your locality and house. Once they are convinced, then they chart out their plan and execute it after getting to know if you’ll be around on a weekend or so.
It is at this juncture that Facebook’s improved privacy settings would help you choose what others will view. So, if you don’t know someone on Facebook, just don’t add them!
