Unfortunately my instance (https://feddit.de) is not federating with it yet.
Do they need to approve each and every instance manually? I thought it would happen automatically as soon as someone is trying to subscribe to a “channel” of another instance. No?
I’m not familiar with the exact process yet. But doesn’t that mean if you wanted to run an unfederated instance, you’d need to manually block every other instance there is?
It seems to work now, I’m on feddit.de too and I just subscribed to !KDE@lemmy.kde.social
