HB8 requires sites to use "a commercially available database that is regularly used by businesses or governmental entities for the purpose of age and identity verification or...another commercially reasonable method." Sites that fail to comply could face a civil action from the parents of kids who viewed pornography or anyone whose data is unlawfully retained.
In Montana, SB 544 requires sites to verify age by having people provide "a digitized identification card" or access a "commercial age verification system" that checks a government ID or uses some other sort of "commercially reasonable method" to verify someone's age.
In both states, sites are covered by the laws if at least 33.3% of its content is adult in nature.
