2. Subject to appropriations, the patrol shall make registry information regarding a registered sexual offender’s online identifiers available to an entity for the purpose of allowing the entity to prescreen users or for comparison with information held by the entity as provided by this subsection:

(1) The information obtained by an entity from the state sexual offender registry shall not be used for any purpose other than for prescreening its users or comparing the database of registered users of the entity against the list of online identifiers of persons in the state sexual offender registry in order to protect children from online sexual predators. The patrol shall promulgate rules and regulations regarding the release and use of online identifier information. Any rule or portion of a rule, as that term is defined in section 536.010, that is created under the authority delegated in this section shall become effective only if it complies with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028. This section and chapter 536 are nonseverable and if any of the powers vested with the general assembly pursuant to chapter 536 to review, to delay the effective date, or to disapprove and annul a rule are subsequently held unconstitutional, then the grant of rulemaking authority and any rule proposed or adopted after August 28, 2008, shall be invalid and void;

(2) Any entity desiring to prescreen its users or compare its database of registered users to the list of online identifiers of persons in the state sexual offender registry may apply to the patrol to access the information. An entity that complies with the rules and regulations promulgated by the patrol regarding the release and use of the online identifier information and pays the fee established by the patrol may screen new users or compare its database of registered users to the list of online identifiers of persons in the state sexual offender registry as frequently as the patrol may allow for the purpose of identifying a registered user associated with an online identifier contained in the state sexual offender registry;

(3) Any entity complying with this subsection in good faith shall be immune from any civil or criminal liability resulting from:

(a) The entity’s refusal to provide system service to a person on the basis that the entity believed that the person was required to register under sections 589.400 to 589.425;

(b) A person’s criminal or tortious acts when the person is required to register pursuant to sections 589.400 to 589.425, and the person complied with the requirement to register their online identifiers under section 589.407, and committed the criminal or tortious acts against a minor with whom he or she had communicated on the entity’s system by using their registered online identifier; or

(c) Any activity for which the entity would be immune from liability under 47 U.S.C. § 230.
