There is a certain responsibility of IRC users to maintain their own disposition in chat, as well as an operators understanding of maintaining the channel.
To answer your question I suppose it is possible for such an event to occur, via scripted w/dll. Even if that be the case it is still misuse from my own personal perspective, and therefore remains a channel issue.
There is no "auto-entry when the editbox is full" switch in mIRC if that is what you're asking. Some servers provide what is known as a channel shun that prevents a user from input to the channel for the duration of the ban. Maybe that would be an alternative to kicking.
The ircd that I chat on uses this format: /ban ~q:$address($nick,3)
We call it a 'quiet' ban, or q ban.
