Wait what's this about cassandra clare being a plagarist? I only half-read one of her books and it was pretty terrible...
I got a lot of asks about this and I really don’t want to go into it too much cause boy howdy do I not want to bring the wrath of her or her friends anywhere near me. I didn’t survive the fandom wars to go out like this.
I’ll preface this by saying: no one behaved well. There were hackings and threats and fans taking “justice” into their own hands (doxxing), and someone even got thrown out of college because of it and any of us with any sense took several prudent steps back and hid from the fallout that ensued.
CC was a prolific fanfic author for the Harry Potter fandom, she wrote a lot and had a devoted following of fans and while it might seem redundant to accuse a fanfic writer of plagiarism, CC was known for lifting direct lines from other media. Some argue this was part of a “game” like “spot the fandom” sort of thing, but at the time in the 2000s when fanfic sites existed at the mercy of IP holders and without the protection Ao3 affords us, and fanficers were being actively pursued and sued by writers for creating fanfic of their work, these direct “quotes” (and they were not just “quotes”, there were entire paragraphs and pages of her work which if you ran them through plagiarism software it’d spit out entire screeds of other works) was particularly dangerous for fandom and I feel in part goes toward explaining some of the acerbic vitriol aimed towards her—rather than the simple spiteful jealousy her fans like to cite.
There were also some claims that she stole from other fanfic writers, though I can’t find any sources. In fact you will find it remarkably hard to find any “reliable” sources. That’ll happen when you have lawyers and a PR teams to scrub you as clean as they can in order to sell original books.
And while Mortal Instruments seems to be her own work, (debatable given it’s sort of her fanfic work rehashed, so idk how to make head nor tails of that mess) in 2016 the author Sherrilyn Kenyon attempted to sue over her Shadowhunter series for plagiarism, and while certain things were never proved…eh…I haven’t wanted anything to do with her or her fandom since the early 2000s. And that’s all I’m going to say.
