Nexus SMP is a mature and chill Minecraft SMP that is strictly 18+. It runs on Fabric 1.21.11 and it is built for people who want a tight knit group and long term builds where life comes first.
The community is kept smaller on purpose so it does not feel massive or random. They use Ledger so griefing and stealing are easier to deal with and your stuff is safer.
There is also a Creative server that matches the SMP settings so you can test redstone or big builds before you spend materials. They use a few required client side mods like Simple Voice Chat and Discord integration plus some QoL mods and Axiom for the Creative server.
Joining is whitelist only with an application that checks the rules and a short interview with staff to make sure you fit in.
