I understand that Washington State law, RCW 42.56.070.(9) prohibits the use of lists of individuals for "commercial purposes". I understand that the use for "commercial purposes" of said records may also violate the rights of the individual(s) named therein and may subject me to liability for such commercial use. I understand that "commercial purposes" means that the person requesting the record intends that the list will be used for general business purposes, including but not limited to communicating with the individual(s) named in the record for the purpose of facilitating profit expecting activity.
