Kids will absolutely find a way around that. Pornhub and similar sites are nowhere close to real hardcore stuff which I will bet all my money on will not implement age verification. Kids will just shift to less mainstream websites with little or no moderation like allowing zoophilia. Even if they somehow censured it almost all like CP how long do you think it will take them to download Tor or a free VPN harvesting their data? There will definitely be that one kid in 6th grade who will spread the word. Even we as kids browsed darknet that was only out of curiosity. Install spyware on your kid’s hardware if you want them to have hard time bypassing it until of a proper age either by buying their own hardware or being smarter than their parents.

As for disinformation. My discord accounts are getting banned left and right for bot-like activity even though I only use them to separate identities and are 100% human traffic but without a no longer valid email. Idk how scammers bypass it but they probably steal user accounts.

TLDR; It solves nothing but empowers bigger threats even without government overreach.
