I don't even know why the novel I wrote in Red Sleeves Adding Fragrance was reposted by other websites.

The creation of web novels involved copyright issues. Every website had its own way of managing the copyright of the works. The author's copyright usually belonged to the author when he wrote a novel on Red Sleeves Adding Fragrance. However, when an author uploaded a work to another website, the copyright of the work usually belonged to the copyright manager of the uploading website. Therefore, if the novel was reprinted on other websites, the author might not know. This could be because the uploading site had taken copyright protection measures and transferred the copyright of the work to other websites. Or other websites might have directly obtained the copyright of the work and reposted it. Regardless of the situation, if the author is dissatisfied with the work being reposted by other websites, he can try to contact the uploading website or the copyright management to understand the specific situation of the copyright dispute and seek a solution.
