As one of fandom's biggest wank magnets, Claire comes up on FFA from time to time. In April 2013, Gentlefailers discussed at great length the Mortal Instruments movie trailer . Far down in that thread, one nonny linked to this blogger , who claims that Claire's lawyers "are trying to remove any Internet sites which mention her fanfic plagiarism." Not long after, there was another long thread on Cassandra Clare's Gigantic Tourbus .
After reading The Cassandra Claire Plagiarism Debacle (currently only accessible through the Wayback Machine ), a nonny was curious exactly how big/powerful CC was and asked for points of comparison . Meme obliged as best it could, though it was fairly unanimously agreed that no one since has been as influential or widely known.
