We will provide some advice to implementors of software that interacts with the labeling infrastructure on ways to use the labels, but that advice need not be followed.

She is concerned, however, that the children may retrieve text or images or participate in interactive chat sessions that they are not mature enough to handle. The parent installs labeling-compliant browser software on the home computer. Using the computer, the parent reads about several labeling services.
Some services charge a fee for their use, while others are free.
Each service describes its labeling system and illustrates it with examples. For example, some services rate only on the presence of nudity and have very concrete criteria, while others take into account multiple factors. Some services rely on computer analysis of text and images to assign labels, while other services employ people to assign the labels. The parent finds that a service called GoodCleanFun is most compatible with her values. GoodCleanFun employs people to label items by the minimum age of children that should, according to its values, be exposed to the items.
