I don't really see the need to "verify" anything, it's a feature request. If this person says such a circumstance arises when they are using IRC there's no need to investigate it in my opinion.
Anyway, whilst such an option doesn't negatively effect my IRC sessions, I equally don't think it's an option useful enough to have it as default. Out of interest, what does <information> contain? I mean, the message after !nick has to end in a file type (i.e. .mp3) for it to be sent as a private message. If you just sent "!nick sendinfo" or whatever, then mIRC won't send it as a private message. It would have to be a rather rare/specific circumstance for this to actually be a pain for a large number of people.
