My husband once told me about a friend of his who enjoyed photography. They were both students so this was 16+ years ago, when the Internet was nothing like it was now. She noticed lots of traffic on her blog/website and discovered the pictures getting all the attention were of her younger sister in a swimsuit. She took them all down.
Think about technology nowadays. You can search a photo on Google and find out where somewhere is. This is why we don't share information about our children online, nor our location or photos of them or anywhere they go that could identify where we live or they go to school. We also don't 'like' their school, etc on FB. A bit OTT maybe but we don't know how technology will change in the future or what they would feel comfortable sharing online and once that information is out there, it's no longer private. I can't believe that influencers would pimp their children out for some lousy freebies. Most famous people prefer to keep their children's lives private. Not the likes of Hinch, SS, etc.
