Что касаемо серии книг "Орудия смерти", то её я читала основательно, по моему первые две книги.

Draco Sinister, the much-anticipated follow-up to *Draco Dormiens,*raised the stakes: now, Hermione's been kidnapped, and it's up to Malfoy and Harry to rescue her. What follows the kidnapping is your standard action-adventure fanfiction fare, mixed with increasing amounts of erotic subtext and sexual tension. Draco Malfoy was by and large portrayed as a angsty, antiheroic sexpot, which drew even more fans to the trilogy. It even became the trope namer for the TvTrope "Draco in Leather Pants," thanks to a sequence in which Malfoy wears a pair of extremely tight and apparently very flattering leather trousers. But Draco Sinister wasn't all random action scenes and descriptions of hot boys—it was also a lot of uncredited quotes.

See, Cassie Claire did this thing where she included a lot of quotations from her favorite series in her own work, almost always without giving proper credit. This would probably be considered okay if said quotes were things like "may the force be with you!" or other phrases that readers would understand as having come from another work, but they weren't. They were, by and large, random paragraphs and conversations lifted from other pieces of media, including Buffy the Vampire Slayer, Black Adder, Red Dwarf, and various Terry Pratchett novels. Initially, Claire didn't even mention that the quotes were taken from elsewhere, leading fans to believe that particularly profound or witty things were entirely her original work. Eventually, people caught wind of this, and they started to inquire about why some parts of her writing didn't really sound like her at all.

Once people started getting on her case about it, Claire put a general disclaimer at the top of her chapters that certain aspects of her fanfiction were taken from other people's work. Of course, most fans assumed that she meant things like throwaway references, inside jokes, and general concepts. The vast majority of people never thought she was taking full scenes and descriptions and simply changing the characters' names. It didn't help that some of the books Claire took passages from were relatively obscure, and most Harry Potter fans hadn't read or even heard of them.
