I found this server called Anarchy Network and it is a semi anarchy world that tries to feel like pure vanilla survival. It launched in October 2024 and it is hosted in New York City so it feels pretty stable and it is on all the time.
You can join with a ton of Java versions from 1.7.2 up to 1.21.10 and they recommend you use 1.21.10 so stuff works right. The world border is huge with two million blocks so you can run super far and hide if you want.
The gameplay is simple and kind of brutal. There are no map resets and no teleport commands other than a basic spawn command. There is no pay to win at all. Griefing and PVP are fully allowed so bases are never really safe. Nether roof travel is allowed. Phantoms are removed so nights are less annoying and only half the people online have to sleep to skip the night.
Even though it is semi anarchy there are still a few rules. You are not allowed to use dupes or exploits or lag machines. You also cannot spam chat or use harassment or racial slurs. Besides that the server really lets players do what they want and just survive or fight in a big dangerous world.

QuackedSMP Semi Vanilla Duck Mod SMP

QuackedSMP is a survival server that feels mostly vanilla but it also has a required custom mod that adds ducks plus new drops and recipes. The server is made by a solo dev who is building a custom SMP plugin while people play so you get to be part of the first wave testing it.
The gameplay has land claiming to help keep builds safe and it has RPG style stuff like MCMMO type leveling and abilities. There is PvE survival for normal play and there is also a separate PvP arena if you want fights.
They also built anti grief detection and a chat filter so the rules are strict about no griefing or stealing and no cussing and no advertising. Backups run every 4 hours so the world is meant to stay protected. The server runs on version 1.21.8 and it also has a live 3D map you can check outside the game.

Vision Market is a community spot connected with HugoSMP and it is all about strong prices for in game money.
I saw it has around 400 members and they talk about deals like 5 euros for 500k and 38 euros for 5,000,000.
It also says it might sell out soon so it feels limited and kind of rushed like first come first served.
