A rare opportunity to win up to 500 USD with your articles, full details can be found in the link bellow: http://www.camarocarplace.com/win-500-usd/
Are you kidding me...submit up to 20 articles. So that you can not pay for any of them and go ahead and use them all or what?!?! Seriously that's pretty shaddy
On what point r u approving or decline articles??? can you specify..there are so many frauds online which take away your article without paying anything and publish them immediately so you can not use them as unique article that one in decline...your strategy does not work here dude!!
You asking a wrong person, because i just promote their contest. You should use a contact form out there. Also read again everything on their page, because you obviously missed many things. If you article is approved , it will be published on that page, so you can know that it is approved.
