If you wish to remove your server you must take ownership.

There is a seven day wait from joining the site to being able to claim a server. Sorry - no exceptions.

Alternatively you could;
- shut your server down and it will be removed automatically - this might take a while
- change the join port (and query port if applicable) - same result
- block the Gametracker scanners using your firewall

Blocking the scanner IPs should also prevent anyone from re-adding it at another time.

If you are not on a fixed IP address, then simply restarting your router until you have a new IP will accomplish most of the above (aside from the possibility of someone re-adding it with the new IP)
