Article 1

How dangerous are networking sites?
Topic: Legal

Social and ethical concern related to the IT system
¥     Digital citizenship & MySpace because the 13- year-girl has her account on my space and a woman is using MySpace to bully the 13-year-girl so after the woman was bullying the girl, who later committed suicide.

Describe the relationship of one primary stakeholder to the IT system
¥         MySpace because is the social network used to bully the girl, also the social network users because they are prone to be bullied and even the social networks because in every social network this can happen.

The IT concepts and processes 
1.       Account is created using a device with internet access on any browser.
2.       Information is entered in order to create a personal profile
3.       Profile is set and ready for search engines their kids’ online acts.

Explain the relationship between the IT system and the social and ethical concern described in Criterion A
¥     The relation between the IT and the social and ethical concern is that every step that the girl used to create her account is a step that the women use to start knowing everything about the girl and start bullying the girl.

Social and ethical issues
      Cyber bully because the women is using MySpace as a social network to star bullying the girl, fraud because are creating fake profiles to know all the information about any user on social networks and awareness because it was on the conscious of the woman to bully the girl that later  committed suicide.

Evaluate one solution that addresses at least one problem identified in Criterion C.

The solution it could be to track the users activities and provide into law enforcement, so by knowing everything about the person who is bullying another person, you should tell what is happening and demand the case, so the person who is bullying is going to be in trouble.
