For Kids is just about the simplest possible rating system.
Web sites are self-rated by the author of the pages.
To use Safe For Kids you need to download the weburbia.rat file and install it on your system. For Kids scheme, then consult the classification page for instructions. These sites may have content which not all parents consider suitable for children. Examples of content which may be included under this rating are, limited nudity in an artistic or naturist context, drugs avoidance education, sex education for teenagers, games which simulate gambling, games which may be adictive, pen-pal contacts, stories unsuitable for younger children because of some bad language or adult themes, shocking subject such as cruelty to animals, uncontrolled areas such as discussion forums. Since many adult sites do not use the rating systems we advise parents to disallow access to unlabeled sites when children are unsupervised on the internet.
