No provisions of any rule contained in this title shall be construed as giving authority to any commission records or public records officer or employee to give, sell, or provide access to lists of individuals requested for commercial purposes. If a list of individuals is included in the records requested, the commission may require requestors to identify themselves and the purpose of their request, and provide a signed statement that the requestor will not use the list of individuals for commercial purposes.

When the commission has credible indication that a requested list of individuals might be used for commercial purposes, the commission will investigate the request further. The commission will determine on a case-by-case basis whether such further investigation is necessary, based on the identity of the requestor, the nature of the records requested, and any other information available to the commission. When the commission determines further investigation is necessary, the commission will require requestors to identify the purpose of their request.
