How do I make hacks disabled for a world?

[antgame11]

I've tried everything to figure out how to do this, please someone inform me

To disable all hacks, use /map motd -hax
You can add additional words to modify the permission:
(allow staff to hack)
/os map motd -hax +ophax

(allow respawn)
/os map motd -hax +respawn

Use /help map motd
for all possible + or - keywords you can use
