Will not work. None of these kinds of bans has ever worked. Did everyone just forget that they got blackout drunk as minors who could not legally purchase alcohol? Are we under some misguided belief that age verification procedures in this manner can or ever have worked effectively to reduce harm on minors? Will have large unintended consequences far beyond social media access for teenagers. Will actually make the internet less safe for teenagers, as they will now be lying about their age and circumventing the systems in place, which renders all existing protections for them ineffective. Is pointlessly age targeted legislation as social media is also bad for adults as well. Its bad because of business practices and lack of ethical considerations in gigantic monolithic international social media corporations. If your end goal is making the internet safer for teenagers, your end result will actually end up being making the internet safer for everyone.
