It is true that the server-wide rules state that abusing glitches/bugs is not allowed, though any bugs/glitches that aren't caused by the "normal" client specifically found in the vanilla gamemode are allowed to be abused since they would be in a normal "vanilla" world as well.
If you have the server resource pack enabled in your settings, it should automatically apply when you join the GhibliCraft server.
The server IP is Play.GhibliCraft.com and the recommended version is 1.16.4, you'll need a non-cracked Minecraft account to play.
Could you explain the issue with joining the server a bit more? Does the link give any more information other than that?
If you have Discord, you can also reach out to us on the Alan Becker Discord server.
Thanks for asking us first.
You are indeed allowed to use any bugs/glitches and even duping items if you find a way.
Hope this helps,

You're just gonna have to pretend I'm not staff.
