Relationship with Fandom
J.K. Rowling is generally supportive of fan activities; she has given her blessing for fanfiction, saying via a spokesperson she was "flattered people wanted to write their own stories" and "her concern would be to make sure that it remains a non-commercial activity to ensure fans are not exploited and it is not being published in the strict sense of traditional print publishing." 
She gives awards for her favorite fansites, including the HP Alliance , Harry Potter Fan Zone.com (2007), Potterish.com  (2006), The Leaky Cauldron  (2005) and HPANA , MuggleNet , The Harry Potter Lexicon  and Immeritus  (2004).
In 2007 she and Warner Brothers, who hold the film rights, successfully blocked RDR Books from publishing a book version of The Harry Potter Lexicon by Steve Vander Ark. See Harry Potter Lexicon Trial and the Wikipedia article for more information.
In the years since the release of the last movie adaptation of Harry Potter, fandom's relationship to Rowling has been characterised by a number of controversies.
In the aftermath of Rowling declaring Albus Dumbledore gay, there was wank for many years about the appropriateness of only mentioning his sexuality afterwards and not including it in the books themselves. The same controversy flared up again with the release of Fantastic Beasts: The Crimes of Grindelwald, which includes references to the Albus Dumbledore/Gellert Grindelwald relationship but still fails to make the sexuality of either character canon. A similar controversy arose over the relationship between Albus Severus Potter and Scorpius Malfoy in Harry Potter and the Cursed Child which many felt was queerbaited.
Another controversy was sparked by Rowling's writing about North America, made available on Pottermore in 2016. Many fans felt that Rowling had not only displayed a lack of understanding of North America in her worldbuilding, several factors were insensitive towards Native Americans. With the release of Fantastic Beasts and Where to Find Them, criticism only grew, as many took the lack of racial diversity in the movie as further proof of racism on Rowling's part.
In 2018, Rowling liked a couple of transphobic tweets, causing some criticism and wariness of her within the trans community. The issue didn't blow up till late 2019, when Rowling published a tweet in support of Maya Forstater, a trans-exclusionary radical feminist who lost a court case about transphobic remarks as protected speech. In response to Rowling's transphobia, many fans produced fanworks with Harry Potter characters portrayed as trans and the HPTransFest, dedicated to trans Harry Potter fanworks, was started in response.
