Websense Management,
I have a suggestion: draw a category distinction between watching sports and playing sports (or doing healthy activities). Many of your customers probably don’t want employees checking baseball scores, reading about basketball games, etc. (addictive content), while at work, but are likely okay with their employees gathering information about healthy activities (likely non-addictive content). Here are two examples of content that is about doing healthy things (good for employee health, and therefore the bottom line) rather than spending time watching things (bad for the bottom line), that is currently lumped into your blocked “sports” category.

This would allow your customers to more finely tune what they wish to block from their employees.
Thanks!
