I found this server called True Vanilla and it is made for players who really want pure vanilla survival.
It is semi anarchy so griefing and raiding are allowed and pvp is always on and you do not need consent. The only place that is protected from this is the spawn area.
The server is running on version 1.21.11 and it also lets you join with Java versions from 1.20.x up to 1.21.x.
There are two main worlds called Core and Windfall. Core never resets and has extra rules for pvp like no elytra or stasis during combat. Windfall is more wild and only bans combat logging and every month the players vote in a poll if they want that world to reset.
The server does not use claims or voting rewards or special ranks or chat colors so it feels like old school multiplayer where you just play survive fight and build with no extra stuff.
If you miss the freedom of classic vanilla multiplayer this place really tries to be actually vanilla.
