I think there are two use cases: the first is a naive "to prevent pedophiles from having access to children". If you don't think too critically about it, I can understand the enthusiasm for it. The second, and I think potentially more legitimate, is to offer children a space to socialize with their peers without having to worry about parental investigation. Whether or not you agree with the parenting style, it's an underserved market segment. A side benefit could be having your juvenile social media sealed somewhat like juvenile criminal records. Something like offering you the option when you turn 18 to delete your profile, or archive it with read-only access to those over 18. Legally, I think it would face troubles in some countries, but countries with laws granting more self-determination to minors might make it a useful environment for exploring ideas with your peers without constant fear that someone may now, or in the future, be offended by your teenage-angst fueled rants. I know I would have enjoyed that, I had a constant fear of retribution through highschool that prevented me from significantly engaging in social media. It wasn't particularly out of line, the usual "my parents suck, my school sucks, let me be a poorly adjusted adult right now!" kind of thing. But I also grew up during the start of the "social media is forever" age, where it started to be common for years-old social media posts by celebrities to become common. And the posts are always judged by today; not the person you were then, or the environment you were in. Frankly I still maintain very little social media presence. I would love to interact with people like that, but I also know that all it takes is one slip-up or vaguely phrased statement to sink you anymore. I like that this might be am opportunity to let kids be kids, and say the darndest thing; but still allow them to be full-fledged members of an online and in-person community without fear that their half-baked childhood ideas might ruin their future.
