Numerous safety features that Meta has said it has implemented to protect young users on Instagram over the years do not work well or, in some cases, don’t exist, according to a report from child-safety advocacy groups that was corroborated by researchers at Northeastern University.

The report Thursday came from Bejar and the Cybersecurity For Democracy at New York University and Northeastern University, as well as the Molly Rose Foundation, Fairplay and ParentsSOS.

Nearly two-thirds of the social media platform’s safety features were deemed ineffective or were no longer available, according to the report from former Facebook engineering director Arturo Béjar and Cybersecurity for Democracy, a research project from New York University and Northeastern University.
