We established quite a while ago that fanfiction is on-topic. I would therefore expect that people who don't want to see fanfic questions would just ignore the fan-fiction tag and move on.
About a week ago, someone asked this story-ID question:
Harry Potter Fanfic where Harry is impregnated by Draco
The question is clear, gives numerous highly-specific details about the story, and is rather unlikely to match more than one story exactly (though I grant that it will superficially match quite a few stories, because this plot is apparently a thing in the Harry Potter fandom).
At the time of writing, it's sitting at +7/-6. I appreciate that this is not the kind of question that some of us are here to answer. However, as mentioned above, those people can easily ignore the fanfic tag.
Am I missing something, or are these downvotes undeserved?
