Kindle e-Books will p a warning message if they have spelling mistakes or bad formattingost
Starting in February 2016 Amazon will begin warning customers with a message on the sales page of any books that contain errors either in spelling or format. The warning message will be removed as soon as Amazon received an updated file from self-published authors or publishing companies.
The warning system is in two stages.
1. If an e-book only contains a few spelling errors, but is still readable, a simple warning message will appear on the details page of that specific title.
2. If the book has bad formatting issues Amazon will suppress it and the book listing will be removed.
