You can't link your government ID to your social media account. The legislation doesn't allow social media companies to gather this data. It's specifically not allowed.

In other words: this legislation is useless, and entirely stupid, and kids will bypass it trivially. Teenagers are exceptionally good at bypassing that which they find stupid, or gets in their way of what they consider to be fun, or a right.

It doesn’t have to be impossible to bypass. It just has to create friction so less and less kids end up on social media over time.
