Problems with other people posting photos of baby without permission.

Anyone else????

Why do family/friends whoever think it’s ok to post pictures of your baby without your consent??? My fiancé and I can post them because we have private accounts and only people we want can see the photos. Other people are not private and are friends with hundreds of random people. It’s not ok and it pisses me off and they won’t take down the photos!!! Shouldn’t that be illegal without my consent???
