So, one of the most popular fanfics on AO3 about this phenomenon appears to be Harry Potter and the Girl Who Noticed Him. The author is moving at a breakneck pace and seems to have captured JK Rowling's voice pretty well. A scan of his Xitter (foreshadowing is a literary device) indicates that he is most likely a Brit on the cusp of zoomer/millennial so likely grew up with Joanne's stuff. Anyway, that's a lot of comments.

But there was one line in particular in book two that caught my eye, a blatant Ngubu reference:

From what I can tell, the third or fourth most popular Malfoid fanfic on AO3, the most actively updated one, is written by a white nationalist who posts regularly about feeling the hand of God while he writes it. It's a solid read, well done, schizo chud writer who almost certainly lurks the Farms.
