Every large business that has a computer network of its own will have IT employees who can see exactly what is being looked at. They shouldn't do it unless specifically asked to, but they have the power to. There is always the danger that someone is looking over your shoulder at what you are typing, I suspect the judges were not exactly IT literate.
In France, or Italy, they would probably say that the morals of the judge are not relevant - what is required is the ability to see the morals of others objectively.
Maybe it would be safer if all judges were women. They do look at porn apparently, according to surveys, but not as much and in a different way.
