CA SB680

Prohibits social media platforms from using designs, algorithms, or features that knowingly cause child users (under 16 years old) to inflict harm on themselves or others, develop eating disorders, or experience addiction to the platform.

Platforms can avoid violation if they conduct quarterly audits of potentially harmful designs, algorithms, and features, and correct any presenting more than de minimis risk within 60 days of audit completion.

Social media platforms that knowingly and willfully violate these provisions face civil penalties up to $250,000 per violation, injunctions, and awards of litigation costs and attorney's fees.

Only the Attorney General, district attorneys, city attorneys (in cities over 750,000 population), county counsel, and certain city prosecutors may bring enforcement actions, with a four-year statute of limitations.

Does not apply to social media platforms controlled by business entities generating less than $100 million in gross revenue annually and excludes standalone encrypted direct messaging services from the definition of "social media platform."
