Aside from the above raw log data collected for general purposes, page visits do not expose a visitor's identity publicly. Sampled raw log data may include the IP address of any user, but it is not reproduced publicly.
- Additional information is collected. Editors have been advised of the details and have accepted that as part of being an editor.
