Problem of Social Network.

Facebook is the most popular social network of the current time. In modern times, the daily activities of the people are almost incomplete without it. But now some crimes are happening through Facebook. Which we call "Cyber Crime". Which is a very serious crime. These criminals can easily be found in advanced countries. But in the undeveloped country it is not possible. The law enforcing agencies have not yet reached the advanced technology. With which they can identify the culprit. Therefore, all of us have the responsibility to abstain from these criminal acts.
