Well it is possible that someone may have an offensive or rude nickname. If you have children around you, You may not want them to see it. Also you personally might be offended by it. If there is no operator present, You would have to leave. An answer to this would be to have the nick removed from the list. Just because someone would want this, Doesn't mean they "are the one with issues", at all.
I would suggest using /cline to set the offending nickname the same color as your listbox, as a temporary workaround.
Also, if you could apply mIRC's full library of window listbox manipulating commands, to a channel window, it could be very useful to scripters. I am scripter and I know I would find uses for it.
