Musk pledged to cleanse Twitter of child abuse content. It’s been rough going.

Over 120,000 views of a video showing a boy being sexually assaulted. A recommendation engine suggesting that a user follow content related to exploited children. Users continually posting abusive material, delays in taking it down when it is detected and friction with organizations that police it.

All since Elon Musk declared that “removing child exploitation is priority #1” in a tweet in late November.

Under Musk’s ownership, Twitter’s head of safety, Ella Irwin, said she had been moving rapidly to combat child sexual abuse material, which was prevalent on the site — as it is on most tech platforms — under the previous owners. “Twitter 2.0” will be different, the company promised.
