I found DogeM and it is a semi anarchy vanilla server that feels fresh and active. It runs 24/7 so you can hop on whenever.
People are always trying to team up or go solo. You can fight raid loot build and try to take over areas.
The next reset is planned for late May so it still feels worth joining now and getting set up with the community.
DogeM Semi Anarchy Vanilla Takeover
GG.MINEWIND.NET New Server IPSmall Vanilla+ Survival SMP Resetting Soon
This is a small vanilla plus survival server with a few simple mods. It feels pretty chill and focused on building and community.
There are a couple builder teams and some solo builders too. A lot of people are already in endgame so there is a ton of loot around and the world feels very developed.
The server uses the Louieland official modpack. It has waystones and simple voice chat so travel is easier and players can talk in game.
The owner plans to reset the world in February so this is a good time to hop in and enjoy the current map before the fresh start.GG.MINEWIND.NET New Server IP
