The writing is on the wall. Well, the wall of the Internet. A search online reveals that several news agencies, including Time, CNet and Wired, are reporting that the activist group Anonymous threatened to take down Facebook on Nov. 5 unless the gaming company Zynga agrees to discontinue its plans to lay off 1,000 employees. The group said it stole passwords and defaced the NBC video page on Sunday. Gangs have tagged physical brick walls and buildings. Online hackers now believe it's okay to deface online properties. Another publication, examiner.com, reports that the move on NBC was in honor of Guy Fawkes, a conspirator in a plot to blow up Parliament in 1605, according to Time World.
