When I was a manager an employee of mines set up a website showing him with women. It wasn't anything worse than you would see on page 3 of the Sun at that time. But the students found out about it and started putting posters on the walls. I interviewed him and asked him kindly to take his site down as in was not appropriate for a lecturer. He agreed. Then a couple of months later it happened again. I interviewed him again and he agreed to resign. Griffiths seems like that type of guy. They cannot help themselves.
