The same methods that are used for gambling are a good start.

I know lootboxes in video games are regulated in some countries. Not sure if they are banned in some places, but I do know that they have to show the odds in some places, and in others they have to be deterministic.

The crux of the issue is personalization and behavior psychology. If you move to a boring feed design, you end up addressing most of the current issue.

Another option is to allow for interoperability between social media platforms, which is a competition respecting way of giving people the ability to move to platforms that “work” for them better.

I’d hazard that Civil liberties are not really at risk here, only the bottom line of social media platforms. However, theres enough money to protect the bottom line even if it costs civil liberties.
