But isn’t that the wrong approach?

If you want to choose something better, shouldn’t be ‘enshittificationability’ be the main point you want to address? That is the reason discord is doing most of the bad stuff. Proprietary software is about enshittification.

The point I am making is about protecting teens from adults. So teen-per-default means that adults can freely talk to teens, which should be prevented. Either allow no teens on your platform, or teens have to proof that they are teens first.

Adults (and teens for that matter) are pretty good at obfuscating grooming.

So an adult could just create two accounts, one to access teen spaces, where they don’t verify their age l and one for accessing adult spaces, where the age gets verified?

Teamspeak isn’t open source… Use Mumble, MediaMTX or Matrix instead.
