Managers most likely to have porn
I am a retired Sys Admin. We found that men with offices, with a door, were the most likely to have porn on their PCs. 99% of porn is on men's PCs so if you are going to HR go to a woman manager in HR. Our three worst abusers were a manager in IT (most ignorant person in IT), a male manager in HR and another man in a remote office. We could tell that this last man was always on time for work and did not leave early because the logs with URL entries had time stamps. Solid porn from 8 to 5. No one was fired but they were warned and suddenly the porn stopped. There were a lot of red faces.
