I'm using Lemmy, and since I highly doubt the admins will implement the age control thing, the new laws will make it pretty much illegal. So, either:

• They ban it and everyone has to start using a vpn/tor to access it (which would spread the word about it, and many kids would also do it with facebook or twitter or tiktok).
• Or they don't bother about small platforms, in which case kids will flock to those smaller platforms, which now have no incentive at all to care about legality of their content. Congrats, it's worse now.

Requiring easier to use parental controls on phones and tablets is the actual way forward. Maybe they could publish a regularly updated list of what they consider "social media not suitable for kids" and make it the default blocklist when activating parental controls on any device.

I'm also not against regulations that punish platforms for knowingly hosting misinformation, spying on users, or other dark patterns. But a ban on social media which doesn't do age checks will not achieve any of that, it has the opposite effect.
