People would be able to ask for personal data, or information posted when they were children, to be deleted. But just because something doesn’t appear to be online any longer, doesn’t mean it is permanently deleted. Any action we take online has a fingerprint which can be traced. Yes, you can delete a Facebook post, then ask Facebook to delete all trace of it in the profile they have of you… but this information could already have been passed on to third parties, or shared by others. There will still be ways for marketers to track your data.
