If you are worried about send tyoped private messages to the world at large, then you should be using the java chatterbox which, by default, runs in fascist mode, which prevents you from sending mal-formed /cmds to the CB.

It's always annoyed me, because when I want to play around and /rnsg someone, it just so happens that I'm using it at the time and so of course it won't let me, until I turn the option off. Then I'll be in the ordinary CB, and I'll reply to a private message, and leave off the /msg foo, and reply to the world at large. I just can't win.
