*sigh*

no, keyclone had no part in the system getting hacked (unless you didn't pause your keyclone while typing a password into one wow.. while in /say in another...)

i would also say that just about all multiboxers should try to get blizzard's authenticator. at that point, you have ZERO chance of losing your account. even if your system does have a keylogger... it won't matter, as the authenticator code changes every couple of seconds.
