I don't think that's an accurate or at least complete characterization - I think it's a little more complicated. Several of the questions in question are well received and several generate really interesting and well up-voted answers!

So if we feel there's an issue, we first comment and explain our concern, then if necessary we flag. But anomalous and different asking behavior does not warrant demonification.
