Also to force ID on all social media accounts by demanding everyone prove they're not a teen.
I feel like trying to make everyone ID on social media for safety reasons is a lost cause because it's not hard to create homespun communication networks now. I've recently been playing around with notification services for my home server's apps, and I had a self-hosted ntfy server running at one point. Every connected device/application is a node on the network, and anything is capable of sending messages that are seen in the topic feed. This isn't designed to be a social networking service, but since you can send messages right from the Android app I started thinking "get some of your friends connected and you could treat this topic section like an informal chat room". It's not decentralized, but you could run it on a Raspberry PI or any cheap PC on eBay with SSL for secure communication across the wider Net.
Any group that wants to be able to chat anonymously can do something like this and just avoid the normal commercially-controlled services.
