I found a small survival multiplayer server run by a group based in Australia with players from other places too. It is an 18 plus place so they want mature people who just want to hang out and play in their free time.
The server is vanilla and it is mainly about building and redstone. People team up to make cool bases and big farms together.
There is no land claim but they can rollback damage and ban players who do not respect others. They also use some social mods like proximity chat a live map and distant horizons. These are meant to make it more fun without changing the vanilla gameplay.
The group has been hosting SMP servers for almost five years. This world is a few months old and they are still bringing in new players.
