This is a vanilla survival SMP called GOOMB SMP and it just had a fresh reset. The world is amplified so the terrain looks super crazy and tall and everyone is starting tiny bases right now.

There is a 2k by 2k world border so players are kind of packed together near spawn. People are making bases close to each other and sometimes even teaming up. The plan is that the border will expand later so there will be more room for big projects and different ideas.

The community is really active on Discord. People are sharing screenshots of the amplified terrain and planning shops and trading deals. It feels like the start of a new season where everyone is excited and setting up their place.

The rules are pretty strict about being respectful. No racism or hate speech and no NSFW stuff. They want the server to stay drama free and mature. There is no griefing or stealing and no PvP unless both people agree so it is pretty safe to build.

To join you first apply to get into the Discord. Then the moderators check your application and if you are accepted you can send your name to get whitelisted. It seems like a good place if you want a clean vanilla amplified SMP with a close community and a fresh season two.
