I agree with that. If profiling-based ads were allowed, minors would no longer receive ads for booze and porn. They'd have to ask their older brother about the real internet, which is embarrassing.
It goes well beyond booze and porn.
Or find it themselves.
Good thing no one did that in the mid-00s. Nope. Nobody. God, can you imagine if they had?
Meta profiled for vulnerable, low self-esteem minors (eg by monitoring added and quickly removed photos). It was used by advisers to push ads for beauty & lifestyle products feeding on depressed teenagers. Booze is non issue compared to that.
