Ella Irwin, the head of trust and safety at Twitter, announced her resignation.
Since billionaire Elon Musk acquired the social media platform in October, the firm has come under fire for its inadequate measures to block harmful information.
When Yoel Roth quit as head of the trust and safety team in November, Irwin, who joined Twitter in June 2022, assumed over. She managed the moderation of content.
Since being acquired by Musk, Twitter has drastically reduced costs and let go of thousands of staff members, many of whom were involved in initiatives to thwart harmful and unlawful content, safeguard the integrity of elections, and present factual information on the platform.
To combat false information on Twitter, Musk has promoted a tool called Community Notes, which enables people to provide context to tweets.
Irwin’s exit occurs as the platform struggles to retain advertisers as businesses are leery of having their products appear next to inappropriate content.
Linda Yaccarino, a former executive in charge of advertising at NBCUniversal, was named by Musk earlier this month as Twitter’s next CEO.
