Sorry, edit button does not work for me. (Failure of using proxies...)
You may be worrying too much for DDoS attacks. Pretty much none of the servers (including Knight-Empire at the worst times, since you played it) went down because of DDoS attacks. They went down because of the Ebenezer/Aujard exploits, which seemed as DDoS attack. I really don't think a hacker group would DDoS Ko4Life till it goes down. Even if they do, just IP Ban after that so it will be more understandable.
By the way, as I mentioned before, the Turkish newbies won't handle Ko4Life rates. They will give up before they even reach level 10. Just a random VPS PK server with +5 uniques/+10 items is what they want.
