rewriting software-

Do not use spinners, they are harmful to your online presence and reputation and produce very poor quality articles. I have only found one paid rewriter, that makes the article at least readable (obviously I do not share its name), but the only use would be the mass article directory submission, which would get you some PR0-PR1 backlinks, so not effective at all. If you want to rewrite an article you already wrote, do it yourself or pay someone else and do not make more than 2 copies. Instead of trying to duplicate your content and passing duplicate check, why not just write quality articles and submit them to EzineArticles or other popular directory? Your content will get syndicated resulting quality backlinks. I am totally against spinners, rewriters and content generators. Sorry.
