Overusing social media could be solved via e.g. Screen Time or a similar time-limiting solution (perhaps w/o an option to "snooze" the daily limit if a parent set it on a child's device).
I hate it and will gladly dance on its grave for those reasons alone.
Now the best infinite scroll implementation I've seen is one that has at the top of the window a number of page selectors. When you scroll past a certain point, the next page selector gets highlighted, and the previous content disappears from the DOM content.
Pagination can do this as well, but in this case, I would make fewer clicks.
However, I'm not saying infinite scroll is the best in this use case, but would be a contender - I 'might' prefer it than pagination.
But theres another comment of mine, I say it's the same rationale of banning cigarette ads instead of cigarettes. Which has worked very well for dropping smoking rates from like 50% of the population to now around 14% and still dropping.
