I put it in quotes because I have a hard time considering it "fair" myself. The main point here is: this anti-social behaviour of the Hacker was made possible because of his anonymity. Anonymous towards the legal system but anonymous towards his private life as well. It is fair to assume he kept his cyberbullying activities to himself because she wouldn't support that. The hacker's wife was probably more endangered by continuing to be living next to a criminal.
