Once upon a time there lived a boy. His head was swift such as the wind, although the young boy was little and fragile. He could calculate the results of any problem in the blink of an eye. But that wasn’t his largest talent. No. His biggest talent was perception. The young lad could comprehend and perceive anything faster than anyone he had ever met. Afterward, he fell in love with a beautiful princess. She had magnetic green eyes and light brown hair. He loved her very much and she adored him back even more. There was just one issue – the young boy was the son of a blacksmith. The princess’s father would never allow her to wed a simple son of a blacksmith. However, their love was too powerful. In one fell swoop, the young boy raised an army of undead and began a rebellion to overthrow the evil king who failed to believe in genuine love. After months of fighting against the armies of his love’s dad, the young lad was assassinated as well as the war was over. No songs were sang.
A long time ago right now there lived a boy. He had blue eyes with blond hair as yellowish as gold. The young boy was small and fragile, but his mind was swift just like the wind. He could calculate the outcome of any situation in the blink of an eye. But that had not been his biggest talent. No. His biggest skill was perception. The young boy could understand and perceive anything quicker than anyone he previously ever met. Then, he fell in love with a beautiful princess. She acquired magnetic green eye and light brown locks. He loved her quite definitely and she loved him back more even. There was only 1 problem – the young boy was the son of a blacksmith. The princess’s father could not allow her to marry a straightforward child of a blacksmith. But their love was too strong. In one fell swoop, the young boy raised an army of undead and began a rebellion to overthrow the evil king who did not believe in true love. After months of fighting against the armies of his beloved’s father, the youthful boy was assassinated and the battle was over. No songs were sang.
Think of it this way: What do you have more chance of hitting, a distant, tiny target or the broad side of a barn? For the sake of search engine optimization, you want your website to be the broad side of barn.

Imo it is not possible for google to detect properly spun content, it is not worth computing power it requires. They can do this using ngrams for example, but it is uses a lot of queries. And for example article spinner I coded beats this algo, so google cant detect that the content is spun. Manual spinning is also good but it takes more than 30 minutes per article.
