X has revamped its adult content policy in support of "sexual expression." But its safety measures aren't nearly robust enough, experts said.

The social media platform X says it will now formally allow people to show consensual adult content, as long as it is clearly labeled as such. The move makes official a policy already in place when the platform was known as Twitter, before billionaire Elon Musk purchased it in 2022.

“If you continue to fail marking your posts, we will adjust your account settings for you,” X says in the policy update. X users can report unmarked adult content or other violations using the app’s reporting features; the company added that users may appeal a decision “If you believe we made a mistake.”
