And words entered into that would be prevented from being used in usernames at all, not just in the exact form?

So if I set idiot (or Idiot) from being used in a username, it would prevent the creation of usernames Idiot, uridiot, adminisidiotxx, or Big Idiot?

I saw in the extension page that you can use a file in the wiki to have the list of prohibited words, instead of a MediaWiki page? Is that possible? I would prefer that a list of prohibited words not be publicly accessible for obvious reasons.

I require users to confirm email before being allowed to edit, as a way of preventing spammers from editing. I'm currently under attack from a troll who uses account names as a way of posting obscenities and outing other users when I'm online at the same time as him, and he doesn't have time to confirm his email and spam the wiki before I ban him. I've set a maximum length for usernames, but apparently it's long enough for him to have his way. I've had to disable account creation twice because of him, and it's still disabled until I can figure out a way of dramatically reducing his ability for trolling.
