The voting system, helped along by tireless scolds, does about the best job possible in dealing with the clueless.

I don't think the intersection of the set of the "clueless" people with the set of people that care about their XP is a very big set.

Besides, all that will happen is that people will select a radio button. It doesn't *mean* anything.

Now, if you want something to change, don't reward people who violate the guidelines. How do you do that? Don't answer the questions. How do you enforce not answering the question? Well, luckely, the intersection of the set of people answering with the set of people caring about their XP is much higher. So, penalize people who answer posts that violate posting guidelines. Remove 50% of their XP. Remove 50% of the XP of anyone who has upvoted such a post.
