For example, a note that relates to a map error should be marked resolved once the map has been updated to fix the error. Duplicate or invalid notes should also be marked as resolved. Resolved notes are not removed or deleted. After a period of seven days they are hidden from view. Reporting notes It is also possible to report notes using the »Report this note« link below the first comment (requires log in). This should be done in the case of spam, notes containing abusive or illegal content, or where sensitive or confidential information appears in notes. The data working group will review all reported notes and permanently hide the inappropriate ones. Open Closed
