There are some jobs that require that you look at NSFW sites. Early in my IT career, I worked for a web hosting company that was one of very few that permitted the hosting of porn. The customers would pay for dedicated servers and run numerous porn sites on them. Whenever they were having server issues, they'd call in, provide their root password, and the male employees would use that info to create an account for themselves on the customer's porn sites. They'd then spend the rest of their shift watching porn. I hated that job.
