I asked this a while ago, but when you delete something on FB, the data's probably not completely deleted. There's likely data retained in backups (unless they have some way of pruning your data from backups), and it's likely that your data already sits on an external platform OUTSIDE of Facebook. Unless Facebook requires apps that you connect to to delete your information gathered from Facebook when you delete your FB account or when you disconnect an app, you're likely to have your personal data and likes and comments already somewhere else.
