The review of electronic reading was stricter than paper reading. E-reading platforms usually censor content to ensure that it meets relevant laws, regulations, and ethical standards. In addition, the e-reading platform could also filter inappropriate content through technical means, such as censoring text, pictures, audio, and video. In contrast, paper books usually did not need to be reviewed because paper books could be read directly on the reader. However, the print reading platform would also review the content to ensure that it was legal. In addition, the paper reading platform could also censor the contents of books by filtering out inappropriate content and marking harmful content. Therefore, although both electronic and paper reading required scrutiny, the scrutiny of electronic reading was stricter.
