I haven't heard the term before. I find it uneccessarily pejorative. I share quite a lot about my son online, as he is the most important part of my life and sharing what is important is the point of social media for me. If anyone isn't interested, then they shouldn't be my friend. I can't compartmentalise my life and pretend that my child does not exist. And why should I?
As for safety, predators and paedophiles have existed since the dawn of time and children have always been at risk. I do not believe that the photos and stories I share increase that risk at all. I take sensible precautions but then i do that in all walks of life, not just online.
