I suppose the only reasonable means for this is device-level control by the parents, who are presumably the ones buying the devices in the first place. So Nostr app settings are restricted on the phone, and the kid can't change it.
Y'know, I'm sort of mixed about this.
I think ideally parents should never give their kids a cell phone to begin with. However, I see this as just leading children to use protocols instead of big tech platforms, where I'm sure they'll inevitably encounter some raunchy stuff, whether parents and guardians want it or not.
So this leads me to a question: Since Nostr is KYC-free and always will be, what kind of approach is best to protect minors on Nostr? Will there ever be Nostr Kids accounts? Will it be left up to parental rights? I'd love to hear thoughts from the devs. #AskNostr

Like I said, I don't see the point of why kids should have access to devices. Yeah, you can restrict what apps your kids can access, but there are plenty of times where content slips through the cracks and children get exposed to false negatives.
At this point, I wish we could bring back VHS and DVDs and parents could review everything to make sure content is family-friendly.
