My understanding in this case the social media company is liable for allowing a child to access social media. So is not a crime for a child to use social media.

> Children cannot be left with the responsibility for staying away from platforms they are not allowed to use. That responsibility rests with the companies providing these services. They must implement effective age verification and comply with the law from day one
