The server I'm looking for was a RPG server, It was so big (I think it has 700-800 players everyday?).
it has a very big mining are in black hole and a jail on a ship in one of the white area. You can do fishing and even you can go to moon to mine some expensive things (the space station was close to jail, it was on waterside).
I think I was playing in this server in 2016-2017(?).
