That feature does require chat moderator rights, but no, MeikoBot doesn't automatically kick a user. It needs to be told to do so. It's just that typing  is often quicker than scrolling through the online user's list and clicking "kick".

(Actually it can be set to automatically kick users when saying certain trigger words, which could be words in your filter.)
