From the Wall Street Journal article:
“Those in favor say it’s a great way to help build a community. Others say sharing violates children’s privacy and may have long-term consequences.
The questions get doubly complex when they involve people’s children. A parent on average will post almost 1,000 photos of a child online before the child turns 5, according to a recent survey. Many parents don’t ask children’s permission before posting, and many have never checked their privacy settings—even though photos often contain data about where they were taken.
That leads many privacy advocates to urge restraint on parents. The risks of putting your child in danger now, or embarrassing them later, are too big to ignore, these critics say. The best course is to keep their photos off the Internet.”
