other electronics to the harass an individual or a group. Whereas
real stalking is an activity of unwanted or obsessive observation
by an individual or a group. This activity is also related to the
harassment.
Cyberstalking is related to the virtual reality and stalking is
related to the reality, but both are related to the crime
activities.
Cyberstalking can be done by only well trained and educated
people but stalking is not related to the education.
The main source of cyberstalking is social networking but for
the real stalking the person has to follow the whole routine.
