If only the world weren't so prudish, that could be an option. It's pretty much policy at any company that I've ever heard of to require associates to A. sign a disclaimer saying you will not use computer equipment for personal use and B. take a sexual harassment course during their first 90 days, part of which covers office etiquette in regards to any sort of imagery that could offend and be taken out of context in a sexual nature. Being a male especially this is dangerous in a workplace in The U.S.A.
