In web novels, plagiarism usually referred to the use of the original author's content, structure, or style without the original author's permission. If you published a novel on Sohu, stopped writing halfway, forgot the password, and continued writing on another website, it was not considered plagiarism. This was because the key to copyright protection was the original work, not the publishing platform. Even if you posted your work on other websites, it wouldn't change this fact. Of course, this does not guarantee that other websites will not think that your work is part of them. They may ask you to provide copyright certificates or other documents to confirm the authenticity of your work. But even if your work is found to be plagiarized, you can still claim that it is your own creation because copyright protection does not rely on admitting or denying plagiarism.
