The 'incognito' command was changed so that people who use it are actually
incognito for real. People who use the command do not show up on the who-list
and you cannot be detected by whois. In case there is some confusion here this
includes gods below the level of MS cannot see you with who or whois. Of course
if you choose to narrate those who hear you will learn of your presence.
