Twitter insiders have told the BBC that the company is now much less able to protect users from trolling, state-co-ordinated disinformation and child sexual exploitation. Marianna takes the rest of the Americast team though her BBC Panorama investigation into how one of the world\u2019s most influential social media platforms is being transformed by Elon Musk. And she describes how the Twitter CEO has responded to her online.

Tech journalist and host of the ON podcast, Kara Swisher, also joins Americast to talk about how social media companies could be regulated in the future.

And in the week of International Women\u2019s Day, one of America\u2019s best-known feminist lawyers, Gloria Allred, discusses how far she thinks women\u2019s rights in the US have come in the decades that she has been practicing law.

Americast is presented by North America editor Sarah Smith, Today host Justin Webb, the BBC's social media and disinformation correspondent Marianna Spring, and North America correspondent Anthony Zurcher.
