Instagram is further cracking down on what millions of young people can see on the platform, aligning its “Teen Accounts” safety settings with the guidelines for PG-13 movies.

Instagram will now apply PG-13 content guidelines to all teen accounts, in the platform’s largest update to online safety for young users, Meta announced on Tuesday. The policy seeks to reassure parents and lawmakers as scrutiny grows over teens’ exposure to harmful material on social media.
