I found a server called MinecraftOffline and it runs on 1.21.11. The whole vibe is lifesteal and anarchy so people fight a lot and taking hearts is part of the danger.
It has a zero reset policy so the world is meant to keep going. The server is hosted in Finland which should feel good for players in Europe.
It also says it uses custom plugins. The machine behind it is an Intel Core i7-8700 with 64GB DDR4 RAM and enterprise HDD storage plus a 1 Gbit network.

Stinky SMP is an anarchy style SMP where players can form clans and try to take control.
It feels like the kind of place where you can start a group and try to become the leader while everyone else is doing the same. If you like chaos and clan drama this server is aiming for that vibe.GG.MINEWIND.NET New Server IPFresh 24 7 True Anarchy Chaos
