Is it that insane to try and steer "new members" to the search function? I'm not saying to censor, hinder, stop, limit, or otherwise permanently block a member. Simply add to the registration process an awarenes of the search function. I have come across several that were not aware of it. I truly think it will help alot of these ones with some basics. Anyone can still thread whatever topic they like and we may or may not see a difference, but we will have raised the profile on an excellent tool nonetheless.
Luck has nothing to do with it.
