“It’s hard to imagine a world where kids can enter a store to buy alcohol, go to a nightclub by simply stating that they are old enough, no bouncers, no ID checks, just a simple yes, I am over the age of 18,” but this is what “has been the case online for many years,” said Stage Olsen.

Monday’s guidelines cover how platforms should adapt their systems to better protect kids along a range of services.

The text suggested that platforms do not use browsing behavior in their recommender systems; that they turn off features like streaks and read receipts to decrease the addictiveness of platforms; that they set privacy and security by default in settings, for example making their accounts invisible to other users not in their networks; and that they consider turning off some features like camera access.

The guidelines follow a risk-based approach, meaning platforms can evaluate what possible threats they pose to minors and adopt measures accordingly.

Tech firms launched a last-minute lobbying push arguing that the guidelines still allow for cumbersome fragmentation.
