Hello, I’m having trouble finding a Peertube server. I tried going to peertube.tv, but you can’t register there and some servers require you to be over 18. Ideally, I would like a server where I can create videos on various topics and in different languages without an age restriction. However, I don’t think such servers exist!
Hello and welcome.
It’s great to see people wanting to create new content for the Fediverse.
Did you take a look here for a start ? Trouver une plateforme PeerTube | JoinPeerTube
I already tried this but didn’t find it
I don’t know lots of Peertube servers. And the ones I know are topic specific.
I’m sorry I won’t help you more for now. 
I learned that MakeTube just reopened their registrations. But it’s a themed instanced. I’m not sure it will fit your need.
But it’s a pity MakeTube required for 16 year olds
But he’s good
