For one, I don't think I deserve to be hanged even once. I believe I cannot even be convicted for even minor crimes. Following the law has its benefits, not worrying (about being caught), is a significant one for me.
He exaggerates for effect both in the extent of the crimes and the extent of the punishment but, as a complement to the idea that an employer (if you will, a potentially "unfair judge") can extend their checks from criminal activity to all online activity and in so doing legitimately dismiss an employee, it seems an appropriate "polite" reply to my comment's parent.
