There are many people who still prefer rewriting their articles by hand. They are used to write sentence after sentence and rephrase their content to ensure the quality of writing.

On the other hand, there also exist people who are either too lazy to rewrite their content or they understand the importance of time and hence, they look for an article spinner tool or paraphrasing tool.
Owner is a scammer who has been banned from major SEO forums for fraudulent and deceptive practices. You might be willing to look past the fact that the owner of this product creates fake accounts to post fake reviews and lies about the product if the product itself was actually good, but unfortunately Spinner Chief itself is filled with half baked buggy features (which are advertised as working completely) and can't go more than 10 minutes without crashing. All in all it is a complete waste of money and time.
In this harsh industry who can't implement a small number of extra profit? Another upside will be that you can construct right up your cache of primary subject material and help to increase your good reputation for posting and potentially attract some more significant paying users. Lastly, simply just believe that of the experience you can be developing by owning to groundwork some of the ideas you generate about. You can be, or will be soon, a fountain of inadequate information.
