Parents should be responsible for regulating the access they allow and time that their children spend on social media. There needs to be laws on how addictive social media can be intentionally made by companies.

Furthermore I don't see any reason why any children <16 should be on or have access to Facebook, Twitter, etc...

TLDR: Companies need to be prevented from making their applications excessivly addictive and parents need to parent their children more when it comes to social media.
