parents posting everything about child

Do you think this is okay? I'm personally on the fence about how I feel. On one side the 12 year old seems fine with it but on the other I feel like she will regret sharing these private things. Also people comment very rude things to not only the parents but the children too! I'm concerned if the children see those comments. The parents recorded her trying on her first bras, starting her period, and growing armpit hair.
