In the server /rules it’s written very clearly: no hacking. Hacking is one of the few things that will get you a fast and permanent ban, with no recourse rights.
Today I’ve banned 5 players using Nodus and similar client mods. We have custom written plugins that detect this kind of thing, and everything is logged and reviewed later, even if I’m offline.
So before logging in to the SpaceCraft server make sure you’re clean. It’s not even worth it, you get no in-game advantage in an Island Survival server from hacks.
Have fun, stay safe 🙂
