@mudgeelight I'm pretty sure that it is possible to configure a Mastodon instance to be insular. My instance runs on a DigitalOcean droplet that I use for other things as well for $20/month(cheaper exists).
@mudgeelight That seems like the sanest way to introduce kids to the benefits of social media while shielding them from the stuff they're not ready for. Sadly, I looked through the user options and that functionality is absent, though it would probably be trivial to implement. Let's both poke around and see what we can come up with this week.
