A few years ago, there was a question on a mailing list for topic X, but the question was about unrelated topic Y. The question was nevertheless answered by the people on the topic X mailing list out of the kindness of their hearts (above and beyond the heart-sourced kindness that powers most mailing lists in the first place). I pointed out that the question really had nothing to do with topic X, and consequently the Y-Users list was a better place for the question.

The person responded,

Yes, I know, but X-Users always provides a quick reply and a quick solution.

In other words, the person was sending questions to the X-Users mailing list knowing full well that the question was not appropriate for the mailing list, but just relying on the fact that the members of the X-Users list are kind-hearted people who will help out even if the topic lies outside their area.

I pointed out, "You can call 9-1-1 to get driving directions quickly, but it's probably not the right things to do."
