Easy way to avoid the ban hammer is by alerting GM of what you are doing and how you are doing it , and taking screen shots.

Once they are clear and agree that it is all fine, then you have justification.

Also theres ways of hiding things from warden, and im sure keyclone can just build in a special hide or random header renaming feature for it anyway.

None the less editing the config file is fine.
Editing textures / terrain / dlls / hex / in out stream is not

The Blizzard rep if it was that sent that message proberbally is some junior who didn't know what the hell keyclone was and quickly looked it up and was like BOT BOT BOT ZOMG HAX WTF.

Thats me done [^_^]
