Existing law generally regulates a social media platform, including by requiring a social media platform to clearly and conspicuously state whether it has a mechanism for reporting violent posts that is available to users and nonusers of the social media platform and to include a link to that reporting mechanism, as prescribed. This bill would require a social media platform to maintain a law enforcement contact process that, among other things, makes available a staffed hotline for law enforcement personnel for purposes of receiving, and responding to, requests for information. The bill would, except as prescribed, also require a social media platform to comply with a search warrant within 72 hours if the search warrant is provided to the social media platform by a law enforcement agency, the subject of the search warrant is information associated with an account on the social media platform, and that information is controlled by a user of the social media platform. This bill would not apply to a social media platform with fewer than 1,000,000 discrete monthly users and would make its provisions operative on July 1, 2025.
