I was looking at the stories for Harry Potter, and any time someone had "Hermione" in their summary, the "herm" part would be cut from the summary, and added to the story tags, implying that the story has a hermaphrodite in it. It leaves behind the "ione" part of Hermione's name, though. I'm pretty sure there's a way to add "Hermione" as an exclusion to the tag adding code, but I couldn't tell you exactly how, without knowing which coding language the tagging code is in. Please, see what you can do to fix this.
I've included an image of one instance of this issue. I've checked the main "Harry Potter" archives, and they don't seem to have that issue, though there was one story that still said "Herm" as a tag, despite having Hermione's full first name.
