I think lightningblitz officially explained how to properly rewrite an article. I guess this could be associated with spinning, since you do spin the article first and then rewrite it. Although, I did raise an argument earlier as to why you would turn the article into "junk" and then rewrite it, I believe myself and others have missed a very strong point here.
Google's algorithm is much smarter than copyscape. Where as copyscape merely detects duplicate content by using patterns and word choices, Google can detect a well spun article with perfect grammar as duplicate content. Why? because it uses a much smarter algorithm.
Example sentence: I love writing with a fountain pen.
Spun sentence: I like to write with an ink pen.
Copyscape will not detect this as duplicate but there is a high chance that google would. Replacing words with plurals, synonyms and different verbs is not an effective technique anymore. Google is catching up on this. Just google a term and you'll see many pages with titles that are synonyms. This is also one of the reasons why many keyword research softwares fail to judge the difficulty of a keyword. Even though the exact word does not appear in the title, it's kind of still there. You have to manually check the top results.
Well done lightningblitz, although I still believe that spinning content this way is too much of a hassle. You can read a few articles and then just write up something from scratch consuming the same amount of time as it would take to use this particular method. It may work for people who are not good at english, but again I think that having proper command of the language is one of the prerequisites for successful execution of this method.
