I found a small Minecraft SMP called Anything SMP and it is open to join with no whitelist
The server plans to reset every so often and the community gets to decide what they want next
It is hosted by a 14 year old and it says any ages can play so it sounds pretty chill and just for fun
Small Anything SMP No Whitelist
GG.MINEWIND.NET New Server IPAnything Goes Community SMP Reset
I found a small survival multiplayer world that is run like a community project. It is called Anything SMP and the whole point is that the server gets reset every so often.
The community gets to decide what they want to do each reset. It sounds pretty casual and open and it is welcoming for any ages.
The host says they are 14 and they just want people to have fun.GG.MINEWIND.NET New Server IP
