I found the Shadow SMP and it is a hardcore survival server with no resets. It is made to be a long world where what happens stays there.
It also says there are no rules so people can play however they want. The main thing is trying to escape spawn and survive. You might get out or you might die trying and that is the whole vibe.
It feels like a place for players who want chaos and real danger. If you like hardcore and you do not want the world to wipe then this is that kind of server.
