It's a long, messy tale, and if you don't already know the details you can find them here, here, here, and here.
Briefly, Polgarawolf denied plagiarizing anything, complained on her LJ that her accusers were trolls and bullies, and deleted responses containing proof. She also posted to the thread in stop_plagiarism, threatening to sue for libel if the report on her wasn't removed. (It wasn't and she didn't.)
