I found a vanilla survival SMP that is trying to pull together about 25 to 30 players to start a community driven world.
The vibe is chill and focused on building and playing together. There are clear rules like no PvP unless both people agree. No griefing. Also just respect other players and their builds and boundaries.
If you want a simple vanilla place with a bigger group and basic respect rules this server is aiming for that.
HermitLike Season Two is a HermitCraft inspired SMP where people just build cool stuff and chill together. It is mainly vanilla with a few plugins for quality of life and moderation so it still feels like old school Minecraft.
The server is on 1.21.11 and it supports crossplay so Java and Bedrock players can all join the same world even on console. It is really new and it started on January 30 so you can get in early before the shopping district and the End get opened.
The rules are simple and it is meant to be peaceful. There is no PVP and no stealing and no griefing. There is also no pay to win and no voting and no crates.
People have made a starting village at spawn that you can join. There is an online live map to see what people are building. Staff are active and the community likes to do events and help new players settle in.
Rattata SMP is a 16 plus community survival server that tries to stay as close to vanilla as possible. It is run on Paper and it supports both Java and Bedrock players.
The rules are simple. Do not grief and use common sense. There is no teleporting and there are no changed loot tables or custom world generation so it feels like normal Minecraft.
It runs on hard difficulty and has 33 percent player sleep. There is a live map. It is whitelist only. Simple voice mod is optional. Core Protect is there too with /co i. The server launched Dec 26th.
