I want to use articles written on GoArticles.com on my own site, just want to know if this is legal? what I am going to do is I am going to copy paste the article (with author link) only thing is that author links will be no-follow! let me know please!
You can read GoArticles article re-use guidlines at http://www.goarticles.com/publisher.html . Basically, you can re-use the articles in an unedited form, as long as you include the author resource box.
Providing a back link to the original source and A link to the Author's profile or his/her own blog or site would do more good. It's better to have a communication before hand rather than just copying and pasting the articles.
writing a 500 word article takes a half hour to an hour. WHY plagiarize when it does you no good and nobody wants to read it?
