I could see the similarities between your quizzes, but she put the names in alphabetical order and didn't include some of the names that you included. There are so many Harry Potter name quizzes. Maybe she took inspiration from your quiz and included some of the names she hadn't originally thought of, but anyone can create quizzes on here, so I'd hardly say she "copied" you. The names in the books don't change, so there's only so many ways you can make a quiz like this. Just something to think about.
I know almost all of these names, but I'm not that good at spelling. PLEASE can you add some alternative spellings so that this quiz is actually fun, I ended up quitting after 2 minutes.
