I found a Minecraft Java SMP that is semi vanilla survival on hard mode. It is running on version 1.21.11 and it has achievements enabled.
The server is looking for active long term players and it is adults only which means 18 plus. The world has been running for about one month.
The rules are simple. No griefing no stealing and no cheating. PvP is only allowed if both players agree. There is also 1 player sleep so nights go faster.
