Q:

Discouraging profiles that never follow up on their own questions

I'm not sure whether to describe this as a question or a suggestion, but...
Every so often a question receives some good answers, but the question author never follows up on those, never approves any of them, because he/she doesn't really care.
Sometimes I look at those, then look at the profile of the person who never followed up, only to find out that person is consistently doing it on all the questions he/she ever asked, never approving any answers, even though they are often right to the point.
Is there any provision on Stack Overflow that would discourage such a behavior? And if there isn't, shouldn't there be one?

A:

An accept rate used to be displayed as a form of shaming such askers - see Let's stop displaying a user's accept rate
Fortunately, SE's community preferences have moved to focussing on question content quality rather than the quality of their askers.
