Badges are supposed to encourage positive behavior (this is even in the badges tag description). However, I am having trouble understanding how the badge Unsung Hero (zero score accepted answers: more than 10 and 25% of total) promotes positive behavior.
- Zero score accepted answers: to me, this encourages posting correct answers that are not good answers. For example, code-only or link-only answers or in general answers without explanation. Bonus if the asker has 1 reputation and the question is not good, so that one can ensure that the asker will not be able to upvote the answer.
- More than 10 and 25% of total: the percentage requirement encourages badge hunters to only provide this kind of answers until they get the badge.
My question is then, what kind of positive behavior does "Unsung Hero" reward? Or what is the motivation behind it?
