I read a great article (I don't remember the URI) where it talk about those evil users that are in any forums or Q&A site.
Sometimes we see a new user that need help but at a very low level.
We can help them so they can learn from us. It is a tiny game between we helping them and they helping us. Because they force to us to make more clear and put our skills at proof.
But they are users that really do not want to learn. They are just there saying "Help! Please Help!" and they do never learn to stop saying "Help!"
A great example for this is this user (see the name). This user (and this makes angry) makes me forget about all the rules, concepts, and the spirit of this community asking question like this. The important is not the question, it is the troubleshooting of this, I tried to help him, but him didn't help me to help him!
If you have a suggestion, another philosophy, or anything to say about problems like this, please create a new answer here :)
