I found a survival server called Goblin SMP that feels like it is trying to stay active and fair for a long time.
The world border is massive at 500000 by 500000 and it expands every month so there is always fresh land to explore.
It is player driven survival so you can build explore trade or team up and make alliances. It also keeps the plugins simple so it stays like solid SMP gameplay.
Raiding is allowed but the rules are clear. No x ray or hacked clients and no exploiting or trying to lag the server. Play fair and respect other players.
