Why would K9 block sites like in the categories of
Travel
shopping
news
jokes/humor
religion
arts/entertainment
personals/dating
online games
hate/racism/violence
news/events
Why would K9 block categories like there listed above. I obviously know that porn and nudity is obviously going to be filtered but why filter such categories.
My second question is, why do work places with computers sometime use K9 web filter ?
