users to upload sexually explicit photos and videos, in the four years after Tumblr banned porn altogether, in response to the Stop Enabling Sex Traffickers Act. Many performers use Twitter's service to market and grow their porn businesses, attracting users to paywalled services like OnlyFans, by distributing photos and short video clips as advertisements. In April 2022, Twitter convened a "Red Team" for the project of ACM, "Adult Content Monetization", as it is known internally. Eventually the project was abandoned, because of the difficulty of implementing Real ID. Child sexual exploitation A February 2021 report from the company's Health team begins, "While the amount of CSE (child sexual exploitation) online has grown exponentially, Twitter's investment in technologies to detect and manage the growth has not." Until February 2022, the only way for users to flag illegal content was to flag it as "sensitive media" — a broad category that left much of the worst material not prioritized for moderation. In a February report, employees wrote that Twitter along with other Tech Companies have "accelerated the pace of CSE content creation and distribution to a breaking point where manual detection, review, and investigations no longer scale" by allowing pornography and failing to invest in systems that could effectively monitor it. The working group made several recommendations, but they were not taken up and the group was disbanded. As part of its efforts to monetize porn, Twitter held an internal investigation that reported in April 2022, "Twitter cannot accurately detect child sexual exploitation and non-consensual nudity at scale." John Doe et al vs. Twitter, a civil lawsuit filed in the 9th Circuit Court, alleges that Twitter benefited from sex trafficking and refused to remove the illegal tweets when first informed of them. In an amicus brief filed in the case, the NCMEC said, "The children informed the company that they were minors, that they had been 'baited, harassed, and threatened' into making the videos, that they were victims of 'sex abuse' under investigation by law enforcement" but Twitter failed to remove the videos, "allowing them to be viewed by hundreds of thousands of the platform's users." Some major brands including Dyson, Mazda, Forbes, and PBS Kids suspended their marketing campaigns and pulled their ads from the platform, after an investigation into child porn on twitter showed that Twitter failed to suspend 70% of the accounts that shared or solicited the prohibited content.
