On 24 August 2022, SB-1018, the Platform Accountability and Transparency Act, was amended by the California State Assembly. The Bill requires social media platforms with at least 1 million unique monthly users to make public on an annual basis statistics regarding the extent to which content determined as violating the platform's policies was amplified by platform algorithms before and after such a determination. In addition, the Bill would require online platforms to disaggregate the information by the type of content and category of violated policy. According to the adopted amendment, the platforms will have to disclose the algorithm amplification from 1 October 2024 or before. Finally, in case of non-compliance, platforms face a fine of 100'000 per violation.
