Privacy interest.
(4) Privacy interest. A privacy interest may exist in personal information even though the information has been disclosed at some place and time. If personal information is not freely available from sources other than the Federal Government, a privacy interest exists in its nondisclosure. The fact that the Federal Government expended funds to prepare, index and maintain records on personal information, and the fact that a requester invokes FOIA to obtain these records indicates the information is not freely available.
