Im not being unaware. I can see potential problems. But usually they are not for a picture of a child, but a combination of factors.
As I said I know some people like this. It’s honestly bizarre to watch. They post birth announcements, have public accounts, use photos with smiley face stickers over the children. Tag with identifying info such as names, nicknames and birthdays. Yet decline all photos taken by or posted by anyone else. Thankfully the ones we are pals with are not as controlling as WhatsApp bans. But they do the social media dance and it’s bizarre to see.
But it does irk with some acquaintances we know. Because say for example nursery. They will be receiving pictures of your child, but you’re not allowed to see those pictures because they contain their child. It’s like seriously fuck off. You’re not the queen. No on gives a fuck about your child. They just want to see their own. And your stopping me seeing imagery of mine.
Personally on social media I am not worried about my child’s photos being used wrongly. Because they aren’t identifying. Ie. On my Facebook account (which is private but has far too many people) I don’t do use it. Don’t tag birth announcements, birthdays or anything. If you looked on it you wouldn’t know I have a child. So I don’t have the problem of OP because if his grandma wants to post a picture it doesn’t make a difference. Because how is anyone going to know that’s my child?! It’s just her grandchild unless she’s tagging it with @PigeonLady child born xz.zz.zz. Which obviously she doesn’t because that’s strange behaviour.
I also have a private instagram. For family and close friends only. There’s about 50 people on there. So I have no issue with that.
Unless someone believes that the one pic a grandparent is going to post is going to be pinched by an AI pedofile deepfake. Which is quite frankly insane. Sure it could happen. But out of the millions of pictures of children out there is a it a legitimate and likely risk. Probably not.
So yes I am very aware. Because I have to deal with this as a bystander on a regular basis. And it’s nearly always that the risks are not because of children’s pictures but because of the parents behaviour that I do markdown the people as either potty yet nice, or entirely narcissistic. Because unless you work for mi5 or are in witness protection. That’s 9.9 times out of ten what it is!
