The guy is obviously just spamming the website in an attempt to increase his chances of winning the contest.
Not to mention that his article: http://collegetimes.us/how-to-become-a-teacher/#comments is the same as the article found here: http://www.howtoguides365.com/how-to/become-teacher/
All I did was copy and paste one paragraph in a Google search to come up with that.
I can't prove that he didn't write the original, but it looks fishy to me.
