It is conduct that currently have many parents and relatives of display photos and all kinds of personal details of their sons and daughters... or underage relatives. Many bloggers, youtubers, instagramers, etc. Published almost every day pictures of their children, exposing them without rating the potential consequences for these in your future, you may wish to not have never appeared in social networks and reproach it in adulthood. I am a supporter of that minors must be protected and not exposed.
