I found a semi vanilla PvP server that is inspired by StrengthSMP. The main idea is you get stronger when you kill players so fights keep getting more intense.
If you drop all the way to minus 10 strength you get eliminated and banned. There is also a revive beacon so other players can bring you back and unban you.
It has a custom spawn and a custom nether portal area. The worldborder is huge at 100k by 100k so there is lots of room to play.
The server is planned to launch on 30.01 if enough players join. The host setup says 24GB RAM and an 8 core 16 thread CPU at 4.60 GHz. They also want to run fun events once the server has enough people.

GG.MINEWIND.NET New Server IPDeadly Hardcore One Life Semi Anarchy

This server is for players who actually want survival to matter. It is hardcore with only one life. If you die you are banned and there are no second chances.
The world is semi anarchy. PvP raiding griefing alliances and betrayals are all allowed. Staff does not step in to fix fights wars or politics so players decide what happens.
The map is huge with a 600000 by 600000 world border. There is tons of space for secret bases and long term empires if you can stay alive.
You have to play smart and trust people very carefully. If you waste your first day you probably will not last long. The real question is who can even survive the first week.
