Symbol Definition System administrators have made a definite statement that customers are treated the same regardless of age. Systems won't be listed in this category unless I can get a link to a web document with a specific statement, or an email message I can publish from someone in authority.
System restricts or forbids young users regardless of permission.
Ratings are assigned based on the terms of an ISP's user agreement or on their public policy statement. Some systems say they support youth rights but feel legally obligated to enforce restrictions. These ratings measure a system's willingness to stick its neck out for youth rights, perhaps at risk of being in legal trouble. Talk is cheap. If you use or run an ISP that's not listed, please feel free to send me a note describing your ISP's policy on young users.
