They have already started talking about banning VPNs. It was never about protecting children.

Yes.

“We’re not at all surprised the UK government is deploying this tactic now when the world is paying attention to the horrors unfolding, they’d rather silence the discussion than confront their own complicity,” the moderators of r/IsraelCrimnes told me. “By labeling brutally documented atrocities as ‘mature content’ and gate‑keeping access, they reveal themselves as hypocrites: preaching democracy and human rights abroad while trampling them at home.”

Reddit explained that it will verify users' age by partnering with Persona, an identity verification company that raised $200 million in April in a series D round led by Peter Thiel’s Founders Fund. Persona asks users to upload a selfie or photo ID in order to verify their age. Reddit says it does not have access to these images, and that Persona does not retain those photos for more than seven days. 

Take a deep breath…

EDIT added /s for sarcasm

Remember how everyone was horrified when an authoritarian government like China forced everyone to disclose their identities to get online? You're thinking of Korea, its government required every citizen to have a ten digit online ID until 2008.
