We recommend our users familiarize themselves with Amazon's various guidelines for writing reviews. You can see Amazon's full help article on the subject here.
We at pubby encourage the below practices to keep reviewers' Amazon accounts in good standing:
Reviews may not contain hate speech, sexually explicit content, profanity, or harassment
Reviews must be the genuine opinion of the reader
Reviews should not be generic
Reviews should be lengthy and include a detailed opinion
Reviews should not contain factually incorrect details, such as incorrect character names or plot lines
Reviews on Amazon must be written in supported languages of the Amazon site where it will appear. For example, Amazon.com (US) only supports English and Spanish, so a review written in French would be rejected or deleted by Amazon for this version of the site.
Thank you for abiding by these guidelines!
