I read Pern as a kid, might have been in the fandom if I hadn't been over it by the time I got the internet, but I was... If you remember the "Burned for Fandom" former organization I mentioned awhile back*, it came out of Pern fandom, founded by someone who'd been threatened on account of fan-art commissions IIRC, but I don't think they were actually sued.


(*That was when we were talking about the Japanese use of the word "genre" where Anglophones tend to use "fandom" to categorize fanworks by informing text. As a tangential point of curiosity, since then I've seen Japanese sites use "parody" [or "paro"] in that context without necessarily seeming to indicate that the works were comedic as that term would in English...?)
