The social media giant Facebook Inc said it has invested more than $13 billion in security and safety measures since 2016.

The company's announcement on Tuesday came days after a newspaper reported that the company had failed to fix the ill effects of the platform identified by researchers.

She said her AI technology helped her stop three billion fake accounts in the first half of this year.

Facebook has also removed more than 20 million incorrect posts on COVID-19 and vaccine content.

It now removes 15 times as much content that violates its hate speech standards on Facebook and Instagram when it first started in 2017.
