Protecting Kids Online: Facebook Instagram and Mental Health Harms

QuestionLee asks whether Facebook collects interest-category data on teens for adult products (tobacco, alcohol, drugs, sexual content) even when not currently serving ads against that data.

ResponseDavis doesn't give a direct yes/no on whether interest-category data (including adult-product interests) is still collected on teens even without being used for ad targeting — describes general data categories and the new under-18 ad-targeting restriction, which addresses targeting but not underlying collection.
