reviews can be given by both anonymous and registered users of most sites, and sites are often programmed to notify the author of new feedback, making them a common way for readers and authors online to communicate directly. this system is intended for a type of bond between the reader and the writer, as well as helping the author improve their writing skills through constructive criticism, enabling them to produce a better work next time. occasionally, unmoderated review systems are abused to send flames, spam, or trolling messages. as a result, the author of the story can either disable or enable anonymous reviews, depending on their preference. internet fan fiction allows young writers access to a wider audience for their literary efforts than ever before, resulting in improved literacy.
