Adam Mosseri, the head of Meta’s Instagram, testified during a landmark social media trial in Los Angeles that he disagrees people can be addicted to social media platforms.

Tens of millions of people have quickly signed up to Meta’s new app, Threads, as it aims to compete with Twitter.

The head of a Senate panel examining social media’s negative effects on young people dismissed as a public relations tactic some safety measures announced by Facebook’s popular Instagram platform.

Instagram has launched a feature that urges teenagers to take breaks from the photo-sharing platform and announced other tools aimed at protecting young users from harmful content on the Facebook-owned service.

Instagram is putting a hold on the development of Instagram kids, geared towards children under 13, so it can address concerns about the vulnerability of younger users.

Alexander Koerner/Getty Images(CNN) - Earlier this year, Instagram head Adam Mosseri declared that the social network wants to "lead the fight against online bullying." On Wednesday, the social media platform announced a new effort in that daunting task: It's rolling out globally a feature called "Restrict," a tool it's been testing since July. Instagram's reasoning for developing Restrict is that young Instagram users may be wary of blocking, unfollowing or reporting a bully because it could make the situation worse. Grygiel also encourages Instagram to share what their test results with Restrict showed, such as whether it reduced bullying. In general, Instagram and its parent company Facebook have been experimenting with ways to make the social networks less toxic.

Adam Mosseri, chief of Instagram, wants users to know the service isn't getting ready to use your photos against you. "If you're seeing a meme claiming that Instagram is changing its rules tomorrow, it's not true." Governor Perry said. But an Instagram spokesperson told CNN Business "there is no truth" to the viral meme. Last week, Mosseri announced a new feature that he said would help users easily report Instagram posts containing fake news.
