I found this server that is made just for adults. It is called BadWolfMC and it is only for players who are 18 or older. They actually check your age so it really is a real adult community.
The server feels super chill and relaxed. It is meant to be drama free and welcoming. People seem to come from a lot of different places and backgrounds and the whole vibe is just friendly and calm.
The gameplay is semi vanilla. That means it still feels like normal Minecraft but with a few plugins that make things more fun without changing everything. The server runs on really good hardware so it feels smooth when you play.
You can join from Java or Bedrock and still play together. So it works on computer console and phone which is pretty cool.
There are a bunch of different game modes. They have survival and hardcore and skyblock. There is also acid island one block prison creative and minigames. They also run events a lot like recurring and seasonal stuff and even weekly Bed Wars tournaments and watch parties.
The whole idea is that this is a place for adults to relax have fun and be creative without chaos or kids screaming in chat. It is like an adult Minecraft server paradise if that is what you are looking for.
BadWolfMC 18+ Adult Paradise
GG.MINEWIND.NET New Server IPCampfire SMP 18+ Semi Vanilla
Campfire SMP is a small 18 plus survival server that wants to last for years and not just a month.
The server is semi vanilla and whitelisted and has no resets planned. It runs Purpur 1.21.9 with a few plugins and data packs that add quality of life and admin tools but it still feels like normal survival. There is no tpa and no home so travel and exploring actually matter.
The world border is 20k by 20k so there is still a lot of space to build and it will grow with big updates. There is a shopping district with a diamond based economy plus nether highways a battle arena and a mini games area that the community is building together.
Most players are adults in their 20s and older and they hang out in voice chat a lot while they work on builds or play other games or just talk. It feels like a small tight group where everyone knows each other and new people can fit in fast.
The server is self hosted in Las Vegas and is online pretty much all the time. It also uses things like a map and protection tools to keep builds safe.
If you want an 18 plus small community survival world that aims to be long term and chill this is what Campfire SMP is about.GG.MINEWIND.NET New Server IP
