Just see the screenshot of the Bing preferences page: https://mailarchive.ietf.org/arch/attach/ietf/pngkwLXzM.png So a single bit value might get you to the “moderate” or “strict” settings, even if your profile says that you would like “off”, but that’s not what they want. If they wanted a strictly on/off switch, they would implement it in their profiles, just as Google did. Yoav
