I don't think that the person who asked the question is to know that the answer is wrong. After all, if he's able to judge that, there's no need for him to post the question anyway. The mere fact that he asked is that he doesn't know and is seeking enlightment.
Even bad answers can contain usefull information, especially information about how NOT to do it - after someone corrects the poster of course.
He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.
