There are two key problems with social media. The first is a people problem. Predators, bullying, etc. This is a difficult problem. The furthest I got in ideating on this was some kind of graph-growth limitation: some proof of physical co-presence or chain-of-trust (i.e. approved by a trusted adult) required for friending.

The second is a product problem. Advertising, the 'algorithm', etc. For that, I do have a suggestion: force all social media sites to have ad-free versions which apply to the accounts of under eighteens, and attempt to reduce 'virality': no like buttons, ways to discourage reposts of original content, etc. so the timelines become less engagement driven.
