We don't actually know that she got sent the hard questions.
Does the interviewee go through the original post and look at everything that got a score of 5? That's a fairly low bar to hit, and probably a bit unreasonable.
I think it more likely that one of the editorial types gathered up the questions, using the best spelled of various repeats among questions (ok, that's a stretch), and decided what to send. I don't expect that they'd send anything that was outright abusive, no matter what score the question had, or how many people supported it.
