There is reasonable evidence that this article has been spun. Rewording someone elses writing could be seen as plagiarism.

Some tips to share content and add value:

• Use a few sentences from your source in “quotes.” Use HTML tags or Markdown.
• Linking to your source
• Include your own original thoughts and ideas on what you have shared.

This type of spam is strongly discouraged by the community, and may result in action from the cheetah bot. Plagiarism via translation, transcribing, or word spinning shows a willingness to circumvent detection. This type of spam is dealt with most severely.
