Elon Musk's social platform X, formerly known as Twitter, has appointed Kylie McRoberts as the new head of safety after the position remained vacant for 9 months. McRoberts will be responsible for overseeing content policies and rules on the platform. In addition, Yale Cohen, a former executive at Publicis Groupe SA, has been hired as the head of brand safety and advertiser solutions. The appointments come as X continues to face challenges with content moderation, spread of misinformation, and hate speech under Musk's ownership. The company has experienced a decline in advertising revenue and a loss of major advertisers due to their ads being found next to harmful content. X's revenue primarily comes from advertising. The previous head of safety, Ella Irwin, left the company in June 2023, shortly after Musk criticized the platform's handling of posts about transgender topics. X has also faced legal battles, including a dismissed lawsuit against the non-profit Center for Countering Digital Hate for documenting hate speech on the platform [199009f2] [bc9e2a17].
