A question I asked that springs to mind is https://stackoverflow.com/questions/37554058/fast-display-of...
It was down voted to a negative score initially. People posted irrelevant/unhelpful comments that I had to hurriedly refute before the question was closed and deleted.
To be fair, I have tweaked the question since, so it probably makes more sense than it did when I initially asked it. But I feel that is something the community should help with.
