Do you have a backup before the hacking incident? If not then Mabey you can use World Edit and replace the command blocks and redstone blocks with the block you want.

Hi there @Meglomaniac, you need to create a player report as fast as you can and with including as much detail as you can, which can be found here. I suggest also checking the logs of the server so you can find a UUID or something similar to give over to the Minehut staff, so they can track down and ban the correct person easier. If you need help finding your logs, you can look through this guide I made on this issue here. As for the fixing the server itself, I suggest following @Nutin_rf's advise.
