I'm sorry, the title may not be clear enough (and don't hesitate to edit my post to change it), but let me explain the situation I'm pretty sure a lot of people have already faced.
Here, I've tried to help this man. I've spent two hours, chatting, exchanging mails, and... all in all it happened that I've just done the job for him:
- without any thanks
- without any responses from mail or on stack
So I've decided to help people who show they've either:
- tried to do a lot by themselves and didn't manage to do what they want;
- asked a simple question (= sounds like "do that job for me") but have a good reputation on stackoverflow.
Take a look at the recent questions: there are more and more beginner's questions of people who do not seem to want to help other ones, but only want the other to do their job.
This leads to my question: how about an idea of showing (somewhere, anyhow) that you are willing to help other ones, and not trying to ask something like "hey I'm busy right now, I know a lot of people who could do that job for me, I'll just ask on stackoverflow". Not a badge, but really, a mark, a small exclamation mark close to their icon, I don't, know, but something that says "(s)he helps other ones, you can help h(im|er) safely".
