Kids go to school, have lessons, right ? And few minutes breaks between lessons ? How that parents want to censorship what kids talk about ? Not to mention phones use. And why exactly ?
Thing is as it always is: parents make fundamens in culture/world view eg via their views and religion they subscribe. And then society and reality takes over. What society you have ?
I don't remember this in my late 90s LAN chats.
At home measures are at best a delay, not a fix. What you also have to do is actually communicate with your child. If you're strict about what they can and cannot do on the internet, they will feel shame for doing it anyway, which may also mean they would be too ashamed to talk to their parents if for example they are getting groomed online.
I'm sorry, but if you're threat model is your kid getting a fucking burner phone, I don't know what to tell you.
Even this law won't fix it! Why, couldnt your kid just save up and buy a plane ticket to the US?? Oh no .. we need a global law don't we?
Or, maybe, we throw away that thinking and acknowledge that the problem is not that big and solving 99% of it is MORE than good enough.
Your kid is way more likely to die in a car wreck. Focus on that or something.
Now it's just outright forbidden to have anything with a chat. And no Internet.
The problem is that other 10 year old have mobiles, free PC access, etc, so there constant peer pressure.
