I found a hardcore vanilla SMP that is meant to be simple and not scripted. It also supports cracked Minecraft.
This server is hardcore so dying matters and the world is just normal vanilla. There is no farlands stuff here.
It has a join and play setup with no application. The play style is basically no rules so people can grief bases and kill anyone.
They also said there are only three maces on the server so everyone is going to fight for them. The goal is to hit 100 members by the start of summer and have an active positive community.
Hardcore Vanilla SMP No Rules

GG.MINEWIND.NET New Server IPPotcor Semi Vanilla RP SMP

Potcor is a semi vanilla survival server with roleplay and lore stuff that started on October 25th and it is still going. It is mainly a Java server but it also lets Bedrock players join and it even supports cracked players.
The server is hosted in Asia and most players are from the Philippines. The world has a 25000 by 25000 border so there is a lot of space to explore. It runs on version 1.21.11 and they say anyone can join.
Some items are disabled like end crystals respawn anchors elytra and netherite. There is also a limit of two maces per player. It is still vanilla style though so you have free will to do your own thing.
The rules are simple. Do not grief unless it is justified or important to the lore. Do not make overkill farms. No cheats and be civil.
GG.MINEWIND.NET New Server IPAshenreach Hardcore Survival With Relic Wars

Ashenreach is a survival server where people are not supposed to feel unkillable. There is room for conflict and conquest so you can fight over land and power.
The big thing here is custom relics. Strong items are hidden around the map and you can use a tracking system to hunt them down even if they are in a chest in lava or being carried by someone else.
Enchantments are made super rare on purpose so you cannot just rely on max gear. It feels more like you need planning and positioning and skill. If you want to really win you will probably need allies and numbers and good infrastructure.
Healing is changed to UHC style so you do not regen from food. You need a campfire or golden apples to heal which makes the server slower and more intense.
The world has custom terrain and regions with handmade structures. SimpleVoiceChat is on so you can talk to people in game. There is also a lands plugin for ranks and permissions in your land but it does not fully stop theft so you still have to think ahead.
It is meant to be long term with no resets and no ranks or shop. It supports Java latest version 1.21.11.
GG.MINEWIND.NET New Server IPWindless SMP Unstable Hardcore Survival

Windless SMP is a hardcore server where if you die you get banned. It is made to feel like those unstable hardcore videos but here it is real and not scripted.
There are almost no rules except no cheating. No xray no fly hacks and no racism. If you cheat you get banned very fast. It is supposed to stay fair and fun for everyone.
The server has simple voice chat so you can talk while you play. It is hardcore so every move matters and people have to be careful.
There will be some custom weapons added later when the end opens. There are 10 total custom weapons and only one mace on the whole server. There are click villagers so you can pick them up and there is infinite trading so villagers will not restock.
PVP will be turned on after a couple of days so people can gear up first. The end will open when PVP is enabled so you have time to prepare and then things get crazy.
