Of course, but why post it publicly? I personally keep all my accounts private even though I am not a 13 years old girl, so I don't get why you would expose your children like that

With or without ads, there's gonna be a certain amount of "unwanted attention", if it's publicly available

FTA: "One mother said her account was set to private, but the posts were automatically cross-posting to Threads where they were visible."

With as convoluted as Meta's privacy pages are and how scattered all the settings are, this would be a super easy mistake to make. I could definitely believe that that mother may not have even known what Threads is, much less that her photos were being automatically cross-posted.
