I've signed something similar at other companies. Talking about sex work at a regular company is inappropriate. But discussing an article your co worker wrote about sex workers is okay because it's your job to cover vices.

The agreement protects Vice from being sued for the second scenario, but not the first. Though I've encountered employees who interpret it as "anything goes."

People who work on search engines, build family friendly filters, or categorize apps and movies have to deal with porn. But that doesn't mean employees are allowed to watch porn. One story I heard about Bing is that they go to a covered conference room whenever they need to view adult material. A good idea to not expose porn to bystanders.
