This server is called The Coffee Pot Network and it feels like a small chill place made for adults. It runs a network on version 1.21.1 and has multiple worlds you can hop between. You have to join their greylist through Discord before you can actually build but once you are in any member can promote you so it is pretty relaxed.
The main world is a survival server with light plugins for land claiming and a simple economy. People are building bases farms and trading hubs there so it feels like a normal SMP but with some protection. There is also a creative world where you get a big claim and can test huge builds or designs before using them in survival.
They have a hardcore world where if anyone dies the whole world gets wiped and restarted. So everyone has to play super careful together. There is also an exploration world that is an old realm kept in adventure mode where you can just walk around and see what was built over the years.
There is a separate modded server running Cobblemon that is whitelisted. They are waiting for a Create mod update before they reset and fully open it but you can ask to be added if you want to play there. Overall the server is pretty small but active and friendly and it looks like they are trying to build a solid adult community instead of just random chaos.
