Removing a hacker's base?

Hackers on my server built a big base, but I don't know how to remove his data base.

Thank you very much for your answer.

English may be bad, I use translation software

 

And how you know they cheated do you have any proof

 

You can try remove hacker base with command: build cube <radius> 0

Use small radius (for example 5-8) to avoid unnecessary erasing other build structures.

This command simply build cube with air. Good luck.
