Comment on List of Predatory Publishers 2014 by Psychology researcher

I came to this website to see about this journal as I am currently reading a paper from the Scientific World Journal (Hindawi). The study seems good, the results legitimate but I was concerned how well it has been edited/reviewed as the standard of English is awful. The authors obviously do not have English as a first language, but it is unusual to see things published that are this poorly written and hard to follow.
