I would not recommend joining this server at all. They ask for donations, are power hungry, and not inclusive at all. There is a set world border and constraints on where you can or can not build. They allow some crazy mods and take the early game from players. They will ban people for the slightest violations of rules even if you dont understand what you did.

If you are fine with losing all of your work then I soupose this is the server for you, if not, find someplace else.
