Q. Am I able to file a FOIA to find out who submitted one on me?
A. Yes. Courts have held that FOIA requesters have no general expectations of privacy regarding their identities. Therefore, you may request an agency's FOIA "log" that lists each request received, and/or seek copies of the relevant requests themselves. Note that personal information about a FOIA requester, such as a home address or telephone number, is likely to withheld.
