Should social-networking sites be censored in an effort to stop cyberbullying?

Please I need question plagiarism free.
Our textbook offers excellent examples of real time ethical dilemmas.  Use Case 2 beginning on page  42 of our textbook for the content of this DT.  And, use questions 4 and 5 on page 47 (at the end of the case) for discussion.  For your convenience the questions are: “4. Who is ethically responsible for the rise and continuance of cyberbullying?”, and, “5. Should social-networking sites be censored in an effort to stop cyberbullying?” to guide your discussion post and your replies to your groupmates.
