You can disable #kill, #summon, etc. This will prevent users from using #kill, #summon, etc.
However, if you are a status 80 user (or above), there is another way to execute these commands: /kill, /summon, /lastname, etc. It drove me nuts on my server, where people were status 80 by default. No matter how hard I tried to restrict the # commands, people were still exhibiting the behavior. Someone finally squealed that the '/' commands are not the same as the '#' commands. Changed default status to 20, and it hasn't been a problem since.
