Twitter has laid off 50% of its employees, the company’s head of safety and integrity said on Friday in a tweet, while saying that the social media platform’s content moderation capabilities remained in place.

The tweet by safety and integrity head Yoel Roth moved to reassure users and advertisers following the company’s takeover by billionaire Elon Musk.

“Again, to be crystal clear, Twitter’s strong commitment to content moderation remains absolutely unchanged,” Musk tweeted shortly after Roth’s own tweet.

Roth said 15% of Twitter’s employees on the trust and safety team, which is responsible for preventing the spread of misinformation and harmful content, were laid off.
