The reason why many mobile novel websites required users to pay to read the full text was that these websites needed to obtain a certain amount of income from the user's traffic. Paying to read could allow users to spend less traffic fees and increase the website's profit. In addition, some mobile novel websites may have copyright issues. If the user shares the novel content without authorization, it may involve copyright disputes. Therefore, in order to protect the website and the author's intellectual property rights, mobile novel websites usually required users to pay before they could read the full text. Paying to read was a reasonable business model. It could also provide users with a better reading experience and make users more willing to spend time on the website.
