Pornography is the most censored type of Internet content at work, according to those clever people at Datamonitor.

Oh come off it now, is that right? Can porn really be more censored than, say, oh, I don't know, Web content about knitting? Or butterflies?

According to the survey, more than half of those companies quizzed restrict access to porn at work. The reason? They're concerned about the threat of litigation from "sensitive employees" who might be offended by the presence of adult content.

A third of companies use written company policies to ward off wayward employees from viewing porn at work, although Datamonitor warns that many employees simply ignore this. Others use technology to restrict access.

A fifth of companies hand check Internet history files to see what their employees have been up to.

Look, I'm gonna have to call it a day there. I can't go on. I still can't get over the fact that porn is the most censored content at work. It's the shock you see... ®
