I found a small Towny and SMP server called GamerHub Towny that is meant to be super chill. The big focus is no grief and no stealing so people can just build and relax.
Players mostly work on towns and try to grow them over time. There is also money ranks and towns to compete for so you always have something to aim at.
It has jobs and MCMMO and an in game ranking system. You can play on a vanilla map and there is also an Earth map option.
Trading is a big part too with player warps and player shops plus a sell only server shop. The community is friendly and active across AU EU and US timezones.
